The Python "Queue" module is designed for communicating between threads 
of a single process.  It relies on a common memory space.

For interprocess communication, you'll need to use a different scheme.  
On Windows, you can try to use a named pipe or a mailslot, or even spawn 
a message loop and exchange window messages.  Or, you could take a 
cross-platform approach and use sockets.

You might try to Google for "python ipc"; I found a couple of good hits 
in the first couple of pages.
