should work (assuming you trust the various systems involved, and your 
own ability to avoid deploying broken code)

but using a custom protocol for this sounds like a slight overkill, 
though.  I would probably use rsync (over ssh) at regular intervals, or, 
if we're only talking about small amounts of code, a bootstrap script 
that fetches the current version over http(s) every time the server starts.

(in the http case, you can use etag/if-modified-since to avoid 
downloading things if they haven't changed, but if you're on a fast 
network, that probably won't matter much).
