[Samba] Transparent File Caching

[Ryan Whelan]

This is not really a samba question, but if anyone would know that answer,
it would be this group. :)  Are there any Open Source projects that offer
network file caching for SMB/CIFS? Something like what Squid does for HTTP.

If not, do you think it would be difficult to position Samba into such a
role?  We are going to use Cisco WAAS for branch locations, but I think the
cache in the devices may not be enough for some locations.

Food for thought if nothing else :)
