I have no experience with BGP confederations, so I could easily be wrong, however I was under the impression that the idea that BGP confederations was to reduce the number of iBGP sessions (ie avoid the full mesh iBGP problem), not so much address aggregation itself.
If this is the case, I think there is a need for BGP, or at least the pseudo EBGP connections between the pseudo ASs in your confederation, to carry site-local addressing. Mark.
