Way too much cursing (;-)) Joking aside, that was definitely a case where we said "don't go there".   To the best of my knowledge, there are two network optimization products that do SMB, so it's physically possible.  In our opinion, it was better to use the SMB protocol locally and a different, cached,  protocol over a wide-area network.  I actually prototyped it with Solaris NFS and cachefs, and was pleasantly surprised it worked for a single-writer case. --dave -- David Collier-Brown, | Always do right.
