This is unsurprising. The people good enough to be useful in
development of Snow are also good enough that their time is worth
quite a bit of money--enough that the only way you will get them to
work on it is either a few tens of thousands of dollars at a minimum,
or some sort of non-monetary motivation.

Then you really want a format accepted as an international standard,
not some random creative idea we come up with.

Do you mean backed by more than one company, or backed by no companies
at all? Most standards like MPEG-2, H.264, etc are the former. If
you mean the latter, that's a very bad thing, as it means less effort
spent on optimizing encoders and decoders for that format. A
general-use format sponsored by only a single organization, whether
ffmpeg or On2, is IMO problematic.

Truly royalty-free means patent-free. As mentioned above, this won't happen.

I will probably outright refuse to work on any project that makes that
as a rule.

So, you mean... not Snow.

"Lossless" and "intra-frame-only" have nothing to do with each other.

Restricted Baseline profile?

You mean H.264 MVC (Multi-View Coding)? The spec has already been finalized.
