Spyder's Burner: Supporting PC's

About a month ago I wrote an article about how I found the structure of Beliefs were working in my Burning Wheel game Oasis. T'was a good article and a lot of people seemed to pass it around, but then Andy asked "what about Intra-Party Beliefs? How does this scheme involve anyone else?" I told him I'd think on it and played a session with my "new" ideas in mind, and found out a few things:

1. Each character can really only have ONE goal Belief at a time. It just doesn't feel right to start on a new goal after all the work it takes just to get one off the ground.
2. Only two goals at a time per party, please. Four goals to juggle together is way too bloody much for my poor head. Two, on the other hand, allows for convenient cut-aways without taking up too much time from the other players. 
3. Players should look out for ways to include other players. Yeah, I know, this one's a no brainer, but when you're going on twenty (twenty!) sessions you sometimes build some bad habits.

So what happens with the characters who don't have the two driving goals per session? They swap out their goal Belief with a Party Belief. Find another one of characters that has a goal and write a Belief about him. Make sure it's how you're going to help or hinder that character and then throw it all into motion. The tentpoles make their move, and the supporters react. Switch roles next session. Rinse and repeat. Or something like that, haven't tried the last part yet. But Luke talks about it somewhat in the Burning Wheel: players taking turns switching between the active and supportive roles.
