Chris Larsen was as always very clear and inspiring. He toned down past rethoric against banks but it was natural considering the audience (do a search for one of his Stanford presentation to have a feel for the flip side).

Other than the business model and operational parts it will be interesting to see how Prosper will manage letting banks compete for loans in their marketplace (a possibility Chris mentionned).

One particular aspect to watch will be how their community will react to banks coming in (if banks take too much place in the marketplace the community may well see it negativly and react the same way).

Very intetesting company along with Wesabe.com
