This won't happen anyway, because it's a classic collective choice problem. If all people put some alternative software on their WIFI router at the same time, this fully decentralized mesh web would come into existence at once in most densely populated areas in Europe and the US (all big cities at least), and almost everybody would have an immediate advantage from it. But if only a few people do it first, they'll have tremendous disadvantages from it due to freeriders, abuses, etc. So it won't happen ever.

I remember to have seen a protocol for such ad hoc mesh networks that wasn't even IP-based and could be implemented on most routers. The network can dynamically self-configure, route around failures, and nodes can go in and out of existence whenever they want. It looked pretty cool but unfortunately can't remember where I've seen it. :/
