Congratulations for your work, my friend!
But this way, are you able to control your house from your TV? Or the only way is in that touchscreen?

yes i can control it from TV too.

There is TV-out output on mainboard and it's converted
with UHF convertor to television channel and connected to TV circuits. So on any TV in the house, you can tune a channel 10 and you get same screen as you can see at touchpannel.
Then i have a RF remote controler Harmony1000 which is connected with RF-IR-RS232 to mainboard that you can control application.

So in real life example: sitting in living room and watching TV, feel too cold, so take my H1000 swith to channel 10, increase temp, switch back to TV channel, easy

WoW! Amazing! So, whats your next features list?

You sould take a deep look in MisterHouse, it has a lot of features really nice, and all the code is available to you. The web-interface it has a lot of things (the problem is it uglyness ). It has voice recognition too, you can take a look how they have done it.

on my list are following items:
1/cotrol application remotelly with mobile phone - SMS or WAP
2/add contol for IP CCTV cameras (pan, tilt, zoom, etc)
3/connect with weather station and display wind speed, direction, humidity, rain etc
4/integration with Security System, IR sensors, access keypads, fire alarms, etc.
5/integration of Windows Media Center
6/maybe voice control - i need to deep investigate this

Thats a good list! I wish you luck! So, why are you still reading this? Put your hands on work
I hope you update us.
