For game programming purposes, I was hoping someone could point me to a
technique for sharing objects across Python processes, preferably
without any kind of marshal/unmarshal steps. It's a long shot, I know.
To be viable, I'll need to be able to pass messages between processes
very quickly. For example, It would be simple to paralellize some
graphics calculations over two processors with each process sharing a
common read-only scene data structure; however, a marshalling step in
this kind of process would be too costly.

I've used three of the libraries you mention, however, they are not
very usable for the task I had in mind, but are of course excellent for
other server based programming tasks.

I'm not familiar with the expression 'teaching my grandmother'. What
exactly does it mean?
