GIF is only 8Bpp, i need to also do at least 15Bpp as well,  Plus its
just not very good.

And i've yet to see a single commercial application that supports MNG, I
(or more correctly my users) need to be able to generate animations
using off the shelf tools.  Plus, doesnt MNG use ZLib as its primary
compression technique, like PNG does?

Yes, decoding needs to be quick.  Zlib is too slow.
