Such an "Open" Corporate allows a new synthesis between the collective and the individual which gives us the "Joint" responsibility of a "Partnership" - which is key to collaborative/cooperative partnership working - but without the individual "several" responsibility of partnership.

Do I understand correctly that his "new synthesis" relieves individual members of "joint and several" liability while giving them proportional ownership rights and liabilities?  Is this a provision of the current UK LLP?  Do you know the legal status of this concept in the US?
