Great to hear you guys did well. Unfortunately I can't make it into Bnet (have since long lost my keys and CD cases), but would be up to start a 2-3 person group on Hamachi.
I'm not sure why these things need to be scheduled: it could just be an on-going competition to see which party gets the farthest instead of a race to see who can clear out the acts the fastest. Probably would need to be Hardcore. Progress would be determined by average player level, perhaps? Or maybe number of quests completed. This would let groups get together on their own times, and let new groups join in whenever.
