option 1 -uno auxpow with btc and other coins auxpow with uno << that's the general idea
1. setup other coins auxpow with uno ("an plugin" that they implement into their code)
2. much later (and only if needed) uno forks 2 get auxpow from btc network
3. if it is UNO that forks to have the Auxpow-like-Via then a BTC pool can mine UNO too
this sounds pretty good to me. So our mission is now to convince as many good smaller sha-coins as possible to auxpow with uno, right?
