Great! This is what I was hoping to hear! If the entire file is getting read
into ram anyway, how would I go about making a file server that would send
the files in chunks and not read the whole thing into ram? I think that you
can see me intention here, but I gues I am still not entirely sure how to do
it yet.

And yes Pieter, I am very much interested in seeing your information on how
to best make a zeroMQ file server!
