Dunno... not for a long time. There are no specific plans.

The problem is that *nobody* has a complete DeltaV implementation out
there... neither client nor server. So it's not like we're actually
under any pressure to get there ourselves.

As for plain old WebDAV compatibility, all we're really missing right
now is support for the LOCK and UNLOCK methods; but that hole will be
patched in an upcoming proposal for implementing reserved checkouts.

Google for the vdelta algorithm; that's the binary diff algo that svn
uses internally.

You can't remove data from the repository. You can make it "gone" from
the latest tree, but the data still exists in history.
