Slight correction - the latest CFP beta does not include a HIPS component, the latest CAVS beta does.
The HIPS component in CAVS2 is more application specific than a traditional entry vector focussed HIPS. The HIPS component for the firewall (slated for relase in version 3) is supposed to be the bees knees, but no-one outside of Comodo has seen it yet. Melih seems to have his knickers in a twist (not a picture to conjure with) over it and reckons it has some totally new, innovative protection methods built in.
I guess we’ll all have to wait and see.
P.S. If you do really have three HIPS already installed, its probably a good thing your posting was about rationalisation.
