I don't know what pexpect is/was capable of, since it's not apparently 
part of the current Python distributions.  I thought it had the ability 
to fork or spawn a child process, with pipes connected.

Anyway, subprocess can launch a new process, with pipes optionally 
connected back to your code.  I don't think it can attach to an 
already-running process.

There are things in pywin32 that might help (even for controlling GUI 
programs), but I suspect there'd be a big learning curve.  And of course 
it'd then be very Windows-dependent.

pywin32 - http://python.net/crew/skippy/win32/Downloads.html
or get it as part of the ActiveState python distro.
