It was possible with an older version of bbPress. I don’t think it’s possible with 2.0 yet, but I’d be surprised if there wasn’t a plugin created for it in the near future.
I see, thanks for the reply.
You might be interested in my suggestion for distributed conversations.
This is now possible:

Though it’s still unclear to me whether or not this relies on BuddyPress 1.5, the environment in which this functionality is showcased. It would be a very odd dependency though, so I’m hoping this would also be possible with WP + BBP alone.
For those interested, a plugin is in development that automates the functionality described in Erlend’s link:

Any chance making it so all the comment forums for a multisite installation are handled by one of the sites.
Example
1.abc.com, 2.abc.com, and 3.abc.com have their comments in the forums at forums.abc.com?
@Andre – you’d need to do some switch_to_blog() action to pull it off, but it’s doable.
