Excelent! Content and sevice syndication among Zope sites without going through
RSS or XML-RPC! This will start a snowballing of Zopes 'network effect'  and
increase the value of belonging to the Zope 'network'.

In fact, unless I misunderstand, this will allow Zope applications to not only
expose services to other servers, but will allow truly distributed applications...

Will there be a separate set of permissions to allow/deny objects to be called
like this?

Hmm, what if you have Zope behind Apache running two or more virtual domain names?
can they call each other using this method?
