Ummm... your own IRC server? Seems pretty realtime to me, and quite configurable. Of course, IRC is geared towards group chat, not user-user.

Perhaps include some more details about what your restrictions/requirements are - will the users be web-based? How many concurrent users will you expect online at any given time?

If you're looking for advice from others, it's best to provide as much info as you can.

Sorry for the lack of information, but the engine I'm looking for is web-based and able to do group chat or real time collaboration, and assume the engine can communicate with Ruby On Rails.
