That's issue 525!

Maybe you could donate some design and development resources?

To comment on your ideas:
- Lots of code in libsvn_wc actually presumes these files exist (which
is why I think that in the short term issue 908 is more tractible)
- Mechanisms already exist to retrieve specific files at a given
revision without the need to run a full update (so, technically,
retrieving 1 file should not be a problem)
- Some operations depend on sending deltas, but when a delta is
generated against a zero-length file, this delta does not depend on
the predecessor (since you faked that there was none): this is not the
hard part.
- I'd prefer to work without base files entirely. If someone starts
complaining that *that* doesn't work for him, we can try to figure out
a partial caching implementation. (just IMHO)
- I don't have any ideas on where the setting would be located best
(props or client config). I'd say: at least repository config (which
we don't have) but directory prop would seem fine to me.
- If you can donate anything wrt this issue getting resolved, please
join dev@subversion.tigris.org and start a thread either stating your
plans, or just informing what you can do.

BTW: There could be another concern before moving your binary assets
into subversion: there's no 'svn obliterate' command, so, you can
never remove history from your repository. Especially with art work,
this can make it grow quite a bit.

bye,

Erik.
