Verse is getting closer and it's turning out to be more multifunctional than I thought it would be with each iteration. This time, Nathan Letwory has been experimenting with integrating chat in Blender, based on the Verse protocol.
Through the work of Jiri Hnidek there is support for Verse in Blender (see also this article), for which I did also some work (master server support). Verse has also a chat specification, and based on this I have been working on a chat system in Blender.
The chat system consists of a dedicated verse client, which acts as the chat server, tawkserv is the current reference implementation. Other clients can login to tawkserv and join channels. It looks quite similar to IRC, and with some work tawkserv could also function as a gateway to a real IRC-server, bridging the gap between Verse and IRC.
The work is still in progress, mostly related to using the chat window inside Blender, but on the whole Verse Chat works. The Verse Chat specification will undergo a revision in the near future, but in the meanwhile, check out the screenshots: one and two.
I think it's a pretty wacky idea to build a chat function in Blender, but it does show the flexibility of the Verse protocol. And I know what you're already looking for a download link but no, Verse support is not available in the 2.42a release; you'll need a CVS build for that. Nathan will publish a beta-binary as soon as the text area functions correctly.
