So I am sure someone else mentioned it before, but I would suggest calling this currency “Primo”. First, it sounds like Euro, so you get a bit of association there and second, PPC sounds too much like Power PC to me… but hey this is just my opinion.
I think it sounds cool, “Hey, I’ve got 100 Primos in my wallet”. “How much? Okay, I will send you a Primo for it”.
Anyway, this just came to mind last night so I thought I would share.
