No problems.

Webdav does not specify anything about a local copy but it is quite possible 
to write a client that works with one (see subversion).  Any api we write 
should take into account both possibilities.

Anyway, the idea I had was to extend KIO but not require the use of an 
ioslave; having a separate plugin for the versioning capabilities.  Eg. I 
would supply a plugin + the webdav ioslave, you might supply a plugin which 
makes dcop calls to cervisia.

I'm encouraged by the fact that someone else is interested in this :)  I'll 
think a bit more on this and hopefully come up with something concrete we can 
discuss further.

Cheers,
Hamish.
