Will CQC work for me?

[programmergeek]

I need better web interfaces for my HAI and Elk systems for now I am concentrating on our HAI Demo House as time permits. Specifically a few of our clients want to use there ipad, iphones and various pc to control there environment, It use to be enough to use the HAI screens or sell them a pronto and configure it but no more I need custom solutions on there interfaces, so here are my questions and environment please let me know if CQC can handle this and the stumbling points.

Sorry for the huge scope on this question but I figured I would just put it out there.

Environment:
HAI system and all the toys with it, thermostats, temp sensors, HAI UPB lights,
I would like to display if zones are open or closed like garage doors and occupancy sensors.

Nuvo Gran Concharado

GEO Vision PC based DVR 20 channel. We would like to see the web cams and manage them, also push a front door pick up to the display when the front door bell is rung.

AvCast, AVAtrix Video distribution system

I tunes music server

Logitech Squeezebox

Somphy shades

Other Needs:
Rss feeds to whether, house temp etc, displayed on one screen
Intercom to the touch pannels. I dont' have a solution currently in place for this.
Family Messages, shopping lists, and display email have been other requests.
Different screens for different interface devices, iphone, ipad, pc, blackberry etc.

Thanks in advance for any feedback.
