BuddyPress.org

It’s a shame these workarounds are necessary, but I have managed to link them together by targeting the sql table directly. All I’ve done so far is create a field in each node to hold a Buddy Press group slug.

There is still the matter of creating a Buddy Press group automatically every time a node is created. I just need to spend a little time studying the Buddy Press code, so I’ll be able to use it’s own native functions to do that.
