"LendingClub could code every account as either institutional (LP, LLC, etc.) or retail individuals."
I am not sure this distinction is as clear cut as you think/propose. Myself and two of my "business partners" are operating our P2P account as an LLC. We have an account balance of less than $100k and have never made a loan above $100 and consider ourselves as just three reatail individuals joined at the hips. We do this to allow shared management duties by like thiniking individuals allowing for time off like vacations, etc for the others partners. Of course we could always set up three individual accounts. P2P is not the only small venture we manage this way.
