The co-op part seems entirely independent from the guarantee society part, right?

I advocate partnership frameworks for:

(a) Peer to Peer Credit - the 'Guarantee Society';

(b) Peer to Peer Investment - the 'Capital Partnership'

The latter is essentially a co-operative of owners of capital (investors) sharing revenues or production with a cooperative of users of capital (labour).
