Don't most of these coins have a magic number already assigned that is
unique? (0xD9B4BEF9 for Bitcoin, 0x0709110B for Testnet, FBC0XB6DB for
Litecoin, etc...).  This seems like a good candidate for identifying coins,
and also supports Testnet cases well.  Maybe there are some alts without
such a magic number that might prevent that?
