Hi Patrick and welcome to P2PVenture. We are having BarCamp:BarCampBank3 this week-end and will be discussing the subject. I see that you registered for the event, we'll have the opportunity to meet and discuss further in persons.
I think that a typical BA size is definitely a possibility and requires full analysis. Several people are currently thinking over the subject and some of them will be physically present tomorrow on BarCamp:BarCampBank3.
I'm wondering if there would not be another matching market between very small businesses and former professionals (like a baker who wants to start a new bakery in the regions and looks for money from current and former bakers everywhere in the country).
Both subjects are not mutually exclusive and feedback from online discussions and physical discussions at BarCamp:BarCampBank3 will certainly help to understand how things could be positioned. -- FredericBaud
