WorldForge Community

I can only speak for myself, but we're pretty strained at Worldforge as it is and I'm focusing fully on our current tech, which is centered around the Atlas protocol, the cyphesis server and the Ember and Sear clients. There aren't many currently active developers, even though this is something we're hoping to remedy through participation in the Google Summer of Code as well as some recent additions to the dev team.
Historically Worldforge has acted as a umbrella project for a lot of very diverse projects, some of them with not much in common with other projects. Almost all of these projects are however not developed anymore; the current development occurs solely within the core tech that make up the Mason world. And I do think there's a risk in diluting the project by adding too many unrelated subproject to it, as has happened before.

That being said, our core tech used in Mason is very modular, and the base idea is to allow them to act as standard components for other projects. Our terrain creation library Mercator for example is fully decoupled from our communications protocol and can be used without having to use other Worldforge tech.
I don't know much about Orbitor so I don't know what your needs are. We do however have some very robust libraries for multiplayer communication, mainly through the Atlas protocol and the standard C++ implementation. If you want to integrate your application with Worldforge it might be a good idea to start looking at how to make it talk Atlas. Is that something that you would be interested in?
