I would venture to say no, but only on the basis that Phex is not a client-server application. It's client to client (or peer to peer as it's been called) so there is no "server" to cache the files to. This is the whole basis behind this type of networking.

Now, since we're dealing with software, could it be modified to cache all your files to an alternate site for others to retrieve (or vice versa), sure, but i doubt anyone here will do the work. It's just not practical and it goes completely against the concept of P2P file transfers.

If you are truly in a small office, I recommend having some alternate file replication software installed to copy files between directories. There are hundreds of apps out there for that. Windows has a few functions built in (like offline file settings and briefcase) but you could also use a server OS to do it.
