FileMQ implementation in C

This project is an updated attempt at FileMQ which is a publish-subscribe file service based on 0MQ. The original project resides at http://github.com/zeromq/filemq. The specifications for the FileMQ protocol reside at http://rfc.zeromq.org/spec:35.

The following is an explanation from the original project...

Why FileMQ?

"Request-reply is just a vulgar subclass of publish-subscribe" -- me, in "Software Architecture over 0MQ".

It's the API my 5-year old son can use. It runs on every machine there is. It carries binary objects of any size and format. It plugs into almost every application in existence. Yes, it's your file system.

So this is FileMQ. It's a "chunked, flow-controlled, restartable, cancellable, async, multicast file transfer ØMQ protocol", server and client. The protocol spec is at http://rfc.zeromq.org/spec:19. It's a rough cut, good enough to prove or disprove the concept.

What problems does FileMQ solve? Well, two main things. First, it creates a stupidly simple pub-sub messaging system that literally anyone, and any application can use. You know the 0MQ pub-sub model, where a publisher distributes files to a set of subscribers. The radio broadcast model, where you join at any time, get stuff, then leave when you're bored. That's FileMQ. Second, it wraps this up in a proper server and client that runs in the background. You may get something similar to the DropBox experience but there is no attempt, yet, at full synchronization, and certainly not in both directions.
