I would have built and hosted a CVS repository, but with no positive answer from any external developer it doesn't seem to be worth the effort.
Hey, here _is_ a positive answer. I definitely back a common code base (and CVS would also be fine for the main PD source...), and i already threw in sourceforge.net some months ago. It's just that i'm not too sure whether CVS is better suited than the existing possibilities.
all the best, Thomas
