Thanks for the explanation.
I wish I could combine multiple auxPOW coins but I thought Doge is still the only auxPOW enabled coin right now or am I miss something?
There are others but I haven't looked into them since it requires you to run their wallet and I have limited resources.
Before Doge switched to auxPoW, a few coins were merge-minable with it; PesetaCoin, TacoCoin and UmbrellaLitecoin.
PesetaCoin has been using auxPoW for quite a long time.
