Maybe worth looking at if I can still contact him.

Good point.  How does existing Free Software deal with patents?  I know
OpenSSL provides some patented algorithms, leaving it up to the user to
provide licenses if necessary or not compile them.  And, yes, I know
what a huge pain in the ass they are -- I've been doing my own bit to
try and stop us getting software patents here in the UK.  Would we never
be able to fully implement Java 3D due to patents?  This being a heavy
research area,  no doubt more than 3D compression is covered.

Hmmm... neither have I.  It appears mainly to be a collection of image
operations and wider file format support.
