There are lots of ways to skin this cat. You'll have to balance the
trade-offs in a way that makes the most sense for you.

I personally would never use AMQP for moving around large amounts of bytes.

If I had to do this with AMQP, I'd probably send a message that
contains a URL for each chunk, have the client download them using
HTTP, then stick a load-balancer in front of the file servers.

http://zguide.zeromq.org/hx:chapter7#toc22 is a good starting point
for reliable file transfer using zeromq, though it doesn't get into
any sort of load balancing scenarios (I don't think...it's been
several years since I actually read it).

Good luck,
