I think that calculating deltas is the clients job when he wants to send
info on a new version to the server.
But I still don't understand what sort of resource types you have in
mind which would need different delta calculations.

Well, if the information were calculated on the clinet, it would still have
to be sent to the server to be useful. If the server had to decode the
deltas in order to respond to requests for document revisions, then the
server would have to know the format of the deltas and the contents of the
resources it was required to reconstruct. This is the problem. Different
resource types will require different mechanisms for expressing deltas. For
example, C source code, XML documents, and binary files would all have
different deltas. So introducing a new resource type on the web would
likely require a new delta which would require the WebDAV server to be
updated.
