I agree with all 3, how about:
4. If you want a ruling on a new spell, building, etc, etc is put it up and let the piranha's chew. If it's over powered, etc someone will say, and anyway it could always be tweaked in arrears if it was over/under in the end, but until Bjorn had a chance to make a final decision we could at least agree a broad brush 'sounds ok' sort of deal.
5. Minor NPC's could be assigned to players (those otherwise away from the action) on an honour basis with maybe minor prep notes - much of the NPC banter would be mainly huff and fluff anyway and anything big could be delegated back. It would effectively expand the number of managable nPC's and give people who've found themselves out of the action a way of being involved.
