Can mibbit do realtime collaboration ? Actually the one I need is web based group chat and realtime collaboration, so other than chat the group can do realtime collaboration too.
I search and found Ajax Push Engine, is it belong to Comet ? The exactly technology that I need is group chat or realtime collaboration, does this technology serve well ?
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.
I suggest you read http://guides.rubyonrails.org/getting_started.html then I recommend sitepoint Patrick Lenz - Simply Rails, although it is outdated (rails 2.0.2) but it have a solid simply background on rails knowledge.
