Chatterous's Google Talk integration was so stellar (it's broken most the time now) that our teams used it exclusively for cross-team chat for the past few years. I was one of their biggest fans but now I know they're not giving it much attention anymore. Given that, I really want to see convore integration with jabber/gtalk somehow, but I'm not sure how it would work for rooms+topics versus just rooms.
