Sounds like a very similar setup to what I have, I also have the Prem 48 and Comm IP. Use the comm IP for Wintex, remote monitoring, auto email, etc. I use the Prem to trigger my CCTV to email me shots from all camera when alarm is set off. Also use it linked to my home automation system, just starting with that. I am an electronic / software programmer so always playing with these things, you can do some interesting stuff the the COMMIP webserver too.
Enjoy
Very interesting - any chance of some details of the hardware and software you used to achieve this?
