Rather than storing files in my documents, which are as you said transferred at every logon, it is a better option to store them in a mapped network drive that reconnects at every logon... a different one for every user that connects as U. That way the my documents directory gets transmitted very fast... but the network drive is not transferred.
I hope it helps,

Isn't that typically what the briefcase feature was for?
Having both a remote and local copy of files that could be synchronized?
Why redo network features when something like that would be infinitely easier?
