Even if threads in Perl were like threads in C, how would that help you solve your problem?

You haven't told us what part of the protocol you want to implement, and what the protocol is supposed to achieve. I suggest you draw some ascii-art flow diagrams of the messages to be exchanged between server and client(s).

Also, for any consideration of implementation, tell us which parts are the slow parts. For example shared storage usually has bandwidth and/or latency problems.

From your description, I still see the "server" as one table in a database into which all clients write their MD5s of all files, but you seem to make it something more. Maybe if you tell us the goal, we can tell you a way to it.
