chat api

I am using QTChat module for providing chat functionality on drupal site.Please tell me how it will communicate with android application.
and please tell me what protocol QTChat module used for establishing chatting.

So had a brainstorm, and I'll volunteer to get this rolling, as I'm working on both modules.

As the chatroom api is developed, I'd like to tap into it for the Drupal Media Player. That would open up live chats in the player, ala ustream, but tied to the Drupal user db.

Just putting that out there. This is brainstorm fodder for the future, and I probably won't have time to work on that idea (which will be after both are mature) until later this winter.
