Dirk,
Hi,
Just my 2-cents worth. About a year ago, I was facing similar choices in wired vs wireless choices when we were remodelling the house. Choices for alarm system, audio/visual, lighting, home automation, etc.. After reading/researching for hours, I went with a combo of wired / wireless.
Wired
Wireless technologies (Wifi, z-wave, zigbee, plugwise) are now able to take over many functions of what previously only wired could do. Even so, I decided to invest in laying down cables, because in 2011 some applications still require wiring for quality results:
A. Cat6 cables to as many points as I could think of:
2x behind each (potential) TV location
4x behind home office desk (fixed PC spot, network printer, ....)
Various places around the kitchen (future appliances, future PC,....)
2x to each bedroom
1x to each (potential) IP camera location (inside and outside the house) for Power-Over-Ethernet (POE).
Cellar
Attic
Outside shed ('schuur' in Dutch) / Garage
The installer called my crazy I wanted CAT6 instead of CAT5. He's right in 2011, but I want to be futureproof for the next 10-20 years. Besides the cost difference was, for me, too little.
B. Good quality speaker wire to:
5 spots in the living room (5.1 surround system)
2 spots in the Kitchen
2 spots in 2 Bedrooms
Cellar
C. Good old coax cable to each TV spot.
D. HDMI cable from central location to main TV spot (living room in our case)
E. Node zero
All the above cables end at one central location ('node zero'). In my case it was a cabinet in the hallway. In Holland called 'Meterkast'. I wanted as many 'boxes' as possible to reside in this cabinet instead of cluttering around the TV in the living room or other places in the house. Things such as Cable Box (Ziggo, UPC,..), Stereo Amplifier, WIFI router, Ethernet Switch, etc...
F. Extra Electrical outlets
-Node zero / cabinet in hallway needed about 8 extra outlets
-Also the location where I have my NAS and Home Automation servers
-main TV location. For stuff that can't go into 'Meterkast' such as game consoles (PS3, Wii,) and perhaps Blue Ray player
Location I underestimated:
-Extra outlets where you plan to sit down with you laptop. For us, this was near the kitchen table. My wife and I now 'fight' over the sole outlet there....
-Figure out the location(s) where you will charge your phones, tablets, etc.. and put outlets there
G. Lighting
Most of the lighting locations + lightswitches in our house were in the right location. Those spots that I want to control with home automation I replaced the switches with switchplates with build-in Z-wave capability. Some extra lightswitch locations were added by the electrician.
Some other extra switch locations he did not add because the cost was too high. There I went wireless with battery-operated Z-wave solutions from Merten.
These battery operated Z-wave things have operated 100% reliable with no lag. The standard Z-wave lightswitches as well btw.
Wireless:
H. Alarm system (Visonic)
The house we bought had a 10-year old wired/wireless alarm system in place. Various sensors and wires got damaged during first phase of remodeling. When I spoke to various alarm installers, they told me that most of their new alarm installations for houses is wireless.
I went with Visonic (self-installed) because of
(a) good reviews and
(b) the possibility to read the sensor output (using RFXCom) and using it in home automation (Homeseer in my case).
(c) the level of expertise available in this forum on integrating Visonic with one's home automation system
It's possible to use a home automation system (Homeseer, ....) also as an alarmsystem, but i.m.h.o. it will always be less reliable. Home automation software runs on a PC with all the inherent instabilities. I don't want my alarm to be out of order because of a PC malfunctioning.
I. Non-Alarm sensors (smoke, CO2, water leakage detection)
I took the Visonic sensors and not independent Z-wave one's. Same reason as above, reliability of performance. They must be active 100% of the time, without worrying about rebooting PC's, software bugs, etc... Sensor output through RFXCom can be read into home automation and e-mailed/sms to me.
Other non-alarm sensors (temperature, humidity) I haven't installed yet, but since they are not as critical as above, I will use Z-wave.
J. Lighting control = Z-wave
I don't have any legacy technology (such as X10), and based on reading around, I decided to go with Z-wave for my lighting control. My brand choice is Merten
K. Music = Sonos
A separate wireless network, with stellar performance. We now play much more music than before, simply because it's so easy. Love the Ipad and Android apps
L. Media Server = XBMC
Not yet installed, but some day (I hope)
Will run next to my NAS server and via CAT6 cables hooked up to the TV
M. Remote control for TV, 5.1 Surround,
Harmony 900
That way, I can control all 'the boxes' from my couch when all that hardware stuff is sitting in the cabinet in the hallway

Nice spreadsheet (4 tabs) comparing various technologies. It's from 2008, but still interesting

Hope this helps!
