I believe the C-library libmng is crossplatform (this is how Qt gets its MNG 
support, which works on win32/x11/mac/zaurus).  libmng should cover most 
C/C++ applications, but I'm not sure about other languages like Java ...

I agree.  If adventurous clients wish to use GIF anyway (like I probably will 
do with Psi), they can bite the patent bullet and do a GIF->PNG/MNG 
conversion before publishing.  What do others think?

I'm not sure if we should go there.  Clients should not be required to do 
image checking or reformatting (well, unless they wish to use an unsupported 
image format).

I say that if MNG is acceptable for the JEP, then there should be no need to 
have a separate 'animated' entry.

If the client wishes to use any of these others, it should convert to one of 
the supported formats before publishing.  This keeps our protocol simple.
