I think this is cool, but - "...it is crucial that users take direct peer-to-peer trust relationships seriously" I personally doubt that most people will take it that seriously, especially if they're new and in a position where they find it difficult to make transactions.

How does the network protect against a certain number of 'broken' trusted links?
