How big is 'pretty big'?

Pyro could work just fine for file transfers, depending on the size of 
the files, how often you need to transfer, and the speed of your computer.

But you are correct that Pyro has substantial overhead compared to a 
solution specifically designed for file transfer (such as copying over 
network file system or network shares, ftp, or http). It boils down to:
- reading the whole file into memory before it can be transferred
- needing to pickle/unpickle the file data

This might or might not be an actual problem.

If you really need another protocol for your file transfers, I agree 
with Jean-Paul to just use a HTTP based solution (web server). Or maybe 
simply copy the file over a network share/network filesystem? Both can 
be configured to require proper authentication.
