I don't see this as a routing difficulty since the updated tables would be highly local to the edge routers which would only need to know about the more precise route between peers. BUT I see enormous issues in terms of providing the capability in a secure form that can be successfully enabled by the average end user. Also, this is more than a routing issue since most file sharing involves an itermediary with both edge devices connecting to a remote server. Not only do the edge routers need to be configured for secure edge routing, but the systems need to have applications which would deliver data directly. I think that folks with a requirement for local sharing will figure out a local solution, often sharing an AP and uplink. If there is a business case here, it wouldn't be hard for an enterprising AP vendor to offer APs which create a shared network, perhaps even providing the 'server' component. Could also be a device which has two radios and hence can connect to two (or more) in range networks.
