Over the internet, you really want to use Web Services rather than
CORBA, because CORBA/IIOP uses multiple ports that have to be
explicitly allowed on the firewall ( on both the client and server
side). This is an admin and security issue. (If you are not going
through firewalls then CORBA is a great choice. CORBA can go through
firewalls using IIOP proxies .. however support is incomplete and not
easy.)

Long-term I think SOAP is the way to go, because of the industry
momentum in that direction. An option that you might consider is
linking JPython to IONA Technologies' XMLBus product. Previous
versions of XMLBus were free previews, and current versions have a low
developer cost (I think) Check XMLBus out at
http://www.iona.com/downloads/

AFAIK this should work well.
Cheers,
John
