Actually, AFAIK, ZEO is the only way to have multiple processes accessing a ZODb
concurrently. There really isn't much to 'learning ZEO'.

AMK has a good intro to using the ZODB, which has a ZEO section. I don't have the URL
handy though ... wait, yes I do...

IMO, going the ZEO route would be easier than the xml-rpc route.
