i'm not familiar with python's os/system/exec functions, but i'm willing to
bet that you're running into an issue with how the "system" function works.

look for a function that allows you to spawn an external app, but that
dosen't wait (or require) the child app to return.

i would also suggest that you work with a client/server setup on the same
machine as a test. furthermore, i would suggest that you have your server do
something like print put to a file/cmdline so you can actually verify that
it's working as it should. once that's working well, then hook in the
system/exec/spawn functionality...

good luck

you might want to look at sshd. if you're on a windows box, you may
need cygwin. if you're on linux, you either already have it, or it's in
your package manager.
