you're gonna want to use user_authenticate() instead, but right idea.

But it's not actually "RPC" in a traditional sense. But, I think I see 
what you're saying. It is an extension to HTTP though, in the sense that 
they've added some additional "actions" (i.e. beyond GET / POST / PUT), 
such as PROPLIST, MKCOL, etc.

Yeah, ultimately a full delta-v implementation would be sweet, but for 
now basic upload sounds like it would make lots of folks happy.

The main webdav implementation for php I know of is the pear package:

http://pear.php.net/package/HTTP_WebDAV_Server

which is still labeled as "beta". I'm sure there are others though.
