Locking is part of basic WebDA, it's not added by DeltaV.

While I strongly dislike some of the choices made in WebDA, there is
no doubt that it answers some of the right issues.  Notably it allows
listing the contents of a directory (PROPFIND with Depth=1) and
creating a new directory (MKCOL).  These are the two main reasons why
we cannot replace FTP with HTTP/1.1.

It's not clear to me whether LOCK is useful; working that out will
require checking a few WebDA implementations.  From what I know about
the Apache 2 implementation, I suspect the answer is a qualified no.

OTOH, I'm not sure that DeltaV can be useful.  I'm glad to hear that
some Wiki authors have puzzled this out, but I suspect they've
designed their implementation around DeltaV semantics, rather than the
other way around.

I'd reformulate that: that extending WebDA+V in ways that serve Darcs'
needs might not be worth the trouble.

Well, that would amount to implementing Darcs-SVN interoperability, in
the way I'm doing right now for Git.  It would be slightly more
tricky, but definitely doable.
