Hmm. I think it will be tough to rewrite dce to not use sockets. You might want
to have a look at the openafs windows port.  Similar problems, similar
solutions. I recall that it was tricky, and still not bug-free... One of the key 
problems solved was the addition of the afs filesystem to windows.  There were 
tricky threading issues as I recall.  

Keep in mind, that the more you change, the harder it will be to maintain a
common codebase...
