Re: Fuller WebDAV support

Oh dear, I seem to have completely misunderstood your goals. The page
at http://subversion.tigris.org/webdav-usage.html suggests

  "Version 2.0 of Subversion will address WebDAV interoperability
(Class 1, Class 2, and DeltaV features). Each of the custom features
expected by the client actually has an alternate mechanism available
in DeltaV, but in a much less efficient form.
It is expected that Version 1.0 will support read-only, Class 1 WebDAV
clients. Any "low-hanging fruit" to increase DeltaV interoperability
will be considered."

My hope was that Apple Finder, Windows Explorer and the various Linux
FS mount systems would be able to subscribe to an SVN WebDAV location
and use them as a read/write network drive (i.e. Class 2 WebDAV). When
I tried this on Apple Finder, I noted that modifying anything (or
attempting to create new files) resulted in an error. Are you saying
this *should* work? Apple Finder only works with Class 2 WebDAV.

If SVN WebDAV worked in this way, you could imagine a network drive
that could be accessed like any normal WebDAV folder, yet with full
version support behind the scenes (although admittedly less quality
with the interim versions, and no logs). There are many situations
where this is favourable.
