None of the CORBA implementations for Python are pure Python. Fnorb is
close, but it contains a small amount of C.

However, given that your project requires Python, which is a binary
package, I'm not sure that requiring the installation of another
binary package is a big deal.

If you must stick with pure Python, you might look at these two:

  DOPY:  http://www.users.cloud9.net/~proteus/dopy/welcome.html
  Pyro:  http://www.xs4all.nl/~irmen/pyro.html

They are both Python specific distributed object systems relatively
similar to CORBA. I've no idea what the performance is like, but they
are likely to be faster than the XML based protocols.

Cheers,

Duncan.
