I, too, would love to have this. I settled on WP because of BPs promise to run in wpmu. That promise was inconsistent with the reason for installing wpmu and thus was misleading.

I would hope that the description of bp be changed or the capability to respect the site_id of a multisite install would be reflected in bp some day.

Until then, I am stuck with projects that cannot reach their vision because of limitations “built into” bp. And I am not a strong enough programmer to make the change myself.
