User Relationship and User Activity Block

Just wanna say thanks for such an excellent module. I'm making some headway with it.

So I don't know if this has been implemented yet and I can't see this in the queue. Is there a way to format a block to show the joint activity of both the user (displayed) and all their related (UR) users - ala facebook? I know you're going to want to develop this for 6 but I'm putting this out there anyway since I'll try and port it back to 5 anyway. This is really what I've been trying to get out of this module from the beginning but my efforts at hacking aren't working out too well right now.
