The main issue is that the decision needs to be handled upstream - 
therefore the intermediate upstream exchange (currently a fanout) needs 
to be something a bit smarter, so we need a new 
x-federation-upstream-helper type or something. This then has knock on 
effects in that it would be nice to still support the case where 
federation is not installed upstream, so we need to detect this and fall 
back.

The next release is likely within a week or so, so this will probably 
not happen before then. But the release after that could easily include 
this enhancement.

Cheers, Simon
