Yes. Check out the Software Developers Cooperative at

Under certain interpretations, the SDC license breaches clause 6 of the OSD.
That's all. The SDC still calls its model "open source".

The SDC forum supports that, but of course effort is focused on perfecting the
SDC license (w.r.t. legal text and all sort of commentary).

I'm sorry if I'm repeating information already given by others. I didn't had
time to go through the whole thread.

Hope to see ou in the SDC forum ;-)  From the posts I did read, the SDC is
exactly what you're looking for.
