We do not poll for reading a file; this is for sockets only. When you
want to read X bytes from a file, you just call the read/fread
function.

It uses a PUB SUB model but over ROUTER-DEALER. It doesn't confirm
chunks but when a client (re)connects it tells the server what files
it already has, and the server will send any changes (including failed
files).

Sure... it's wise to start by writing small examples and seeing how they work.
