There are two webdav plug-ins shipped with the Eclipse SDK. The first
is a webdav client API and the other is an example webdav deployment
plug-in.
The dav client does not implement deltav so there is not history command
available. We use it as a deployment client and not for content-management
support.

If all you need is the webdav APIs (RFC 2518) for your content management
support than you can use org.eclipse.webdav as the client API. Otherwise,
if you want deltav support you may have to go with slide instead.

This code is rather simple but not API. You can re-use via copy/paste.

The compare support doesn't rely on IResources at all. You can provide
your own compare inputs that show remote elements instead of local
ones. See the compare examples for the details.

To summarize - it should be doable. First see if the org.eclipse.webdav
API
is sufficient for you use-cases. Then a site explorer is easy to
implement, look
at the current implementation and tweak for your purposes. Add support to
your editors to lock/unlock/put/get at oppurtune times.
