Spinwing:
Did you ask Honeywell - this sort of thing should be pretty easy. I know that Universal had something like a custom database for their UNS-1 system, and I would have thought Honeywell would too.
Have you checked with any folks at Bluecoat Digest? - it's a forum for FMS related stuff - mostly big FW stuff, but the Honeywell is a big FW FMS...
