Yes, mod_dav has a pluggable backend. Since Perl can be embedded (i.e. apps
can call into it to exec code), then you could implement a mod_dav backend
in Perl. That would save you a bunch of time over trying to do all the
protocol work.
The mod_dav in Apache 2.0 has a better dynamic-load plugin/backend story,
but mod_dav 1.0 (which is built for Apache 1.3) still has all the same
features/functionality for backends.

All of this is being developed within the mod_dav as part of Apache 2.0.
Through the plugin mechanism, we'll be using Subversion (SVN)
(http://subversion.tigris.org/) as the backend. SVN will be using DeltaV as
the network protocol, and Apache 2.0 as the network server.
There is also some DeltaV work going on in the CVS version of mod_dav, with
much of the same backend interfaces and code. I wouldn't call any of the
mod_dav DeltaV work "cooked" though.
I'm going to be testing the Apache 2.0 this week and next, for Milestone 2
of Subversion which occurs at the end of next week. M2 will be a very
limited DeltaV server... but that does include checkout and versioning :-)

The intent is to find time to upgrade Apache to use Expat 1.95.0 and axe the
expat-lite stuff. It should work fine (and part of the Expat 1.95 release
was specifically to fix the Apache/mod_perl Expat conflict), but
time/priority just hasn't happened yet. It should over the next couple
weeks, as we're trying to nail down an Apache 2.0 beta and we want to
resolve that problem.

Oracle has built a backend for mod_dav which stores all of the content and
properties into an Oracle database. It should be appearing on the Oracle
Technical Network "real soon now".
So... mod_dav can do it, but yes: it would be C coding rather than Perl :-)
