Thanks for starting a new thread. Some of your sentences are unclear to me, so if I misunderstand a question just rephrase it and I’ll do my best to answer it.

The WordPress.org integration is done through a shared user table and the same settings for cookies. It is a bit of a hack right now because WP and bbPress have a different idea of how those global tables should look and fight to modify them, which is what took down WordPress.org the other day. (It’s very slow to modify the schema of a user table with hundreds of thousands of rows.)

As for running multiple instances of bbPress, on different domains even, we actually did a fair amount of work for that (was going to call it mubb.org) and it’s the code that currently powers TalkPress.com. However it’s not release quality and it becomes moot because once bbPress is a full WP plugin you get multi-site for free from WP’s built-in MS feature, so you could run as many bbPresses as you like from a single install.
