Sounds like it prohibts nothing, just demands that modifications be
submitted to the originator, as in many current licenses.

And indeed this is, to all intents and purposes, identical to the relevant
clause of the GPL - is RMS going to condemn that too?

Again, this is as the GPL - it insists that derivative works use the same
license!!! RMS must be going prematurely senile ;o)

Agreed. It would be nearly reasonable (but still not quite so IMHO) if the
IP action clause only applied to IP relating to the licensed product.

It does sound a bit odd generally, just not quite right. Can't put my finger
on it...

The only way to fix this, which is IMHO The Right Way, is distribute the
fonts separately with a separate license.

Not sure... certainly, it does not affect users who are not distributing
commercially, but that then restricts and differentiates between forms of
use. Not against the OSD, I believe, but not favourable certainly.

And I third that...
