I don't know the internals of RDFSummary, but if it's using a raw 
PersistentMapping, then that's the problem.  PersistentMappings don't 
have any security declarations on them, so they're unusable from 
restricted code (like ZPT, DTML, Scripts).  If you are able to use the 
contents of 'channel' from DTML or a Python Script, then I'm barking up 
the wrong tree.
