Better "linking" of databases/forums - Think Converge with steriods

[Jinkler]

I know this has been requested numerous time before, myself included, some of us wish to be able to better combine multiple forums. I run six forums, if I could share certain subforums etc between domains, it'd be a massive, massive boon.

Is there anything in the 3.2 framework that will assist in this? I'm thinking maybe a revamped IP.Converge or something similar.
