Hello As part of the general theme for the current development cycle, which appears to be "in-tree forks & cruft must die", I have completely removed Inkboard. Here are the reasons.
1. This code is seriously bitrotted and was disabled for a long time, with no one stepping up to put it back into shape. 2. It is behind times. A modern implementation would use something like Telepathy instead of a homegrown XMPP library. 3. Even if it worked, there is a very good chance it would have several remote execution vulnerabilities. 4. I'm not even sure Inkscape is the proper place for such functionality. It's cool, but it looks very much like feature bloat to me. People can do this much better using Google Docs drawings, which can be exported as SVG. 5. The fact that there were no loud complaints about the disappearance of Inkboard around version 0.47 indicates that few people were using it.
Regards, Krzysztof
