[daisy] Multi-Repository to One Wiki

[David Rideau]

Hi everyone,
Very happy to learn about imminent 2.0 release. :-)
A little question : is it possible to configure several repositories 
with different namespaces and administrators to isolate some communities 
and delegate the administration rights, and configure a single wiki 
which can federate the content of these multiple repositories.
I don't know if it's understandable :-)
If it is not possible, would it be hard to implement myself ?
Thanks for advice and sorry for my english...
David
