Alot of members here have been posting here so long and have networked and made friends with quite a few people. I think a instant messenger chat system similar to Gchat and Facebook's where it's docked on the bottom/side of the screen would be very useful and time saving. PM's are kind of a pain in the ass, and the PM box maxes out at ~150? and with a IM feature all messages would be received in real time and it would make the flow of conversation much smoother between the two parties.

of course each user would have like a "buddy list" so not just any random troll can spam t hem with messages, and they could choose to appear online or offline.

I think alot more people would take advantage of this than you think, and to strongly consider implementing something like this into the forums
