Here's the Reader's Digest version:

I am writing an implementation of an API which is encumbered (just like
the OpenGL API is encumbered).  To distribute an implementation, you
must obtain a free (i.e. no money) licence from a certain company who
holds the copyright.

If I want to be able to claim that my code conforms to the API, I will
have to obtain such a licence.  The trouble is, if I release open source,
and someone else wants to fork the tree, they will have to obtain one too.

What open source licences, if any, allow this?  Or is it impossible to
reconcile this requirement with the OSD?

The rest was commentary.

Cheers,
Andrew Bromage
