Well, not only the source is available, but as I understand it, both Purr Data and Pd-L2ork are open to collaboration by anyone who wishes to join forces.

I have the idea that extended's development was highly centralized, not that I mean to imply that this was the intention, but it seems to me that's how it went, so when it was abandoned, it was hard to take it further - I might be totally wrong in my analysis so please feel free to correct me.

What I wanna say is that I just hope more people get involved and collaborate with Purr Data and Pd-L2ork, so it benefits from an actual community effort where development happens faster.

cheers
