News about Fedora coin looks good. But what about new development? https://github.com/invisibel/fedoracoin
I'm worry about difficulty and total coin supply. Looks like it needs to review this parameters in the source code.

UPD: main.h in the source code contains this string:
static const int64 MAX_MONEY = 2500000000 * COIN; // FedoraCoin: maximum of 100B coins (given some randomness), max transaction 500,000,000 for now

What did it mean? Why its commented as 100 billion total coins instead of 500 billions was announced?
