Insteon and Indigo Integration with Honeywell LYNXR-EN alarm

Hi,
Just checking to see whether anyone has tried to integrate Insteon and Indigo with a Honeywell LYNXR-EN alarm system. The alarm system has wireless motion detectors, door/window sensors and heat detectors that communicate with the LYNXR base unit, probably using RF. I just installed Security Spy and wondered if I could integrate everything without having to buy redundant Insteon equipment. Thanks for any help.
