I'm cautious of using human-meaningful identifiers, especially any that
might require a central repository, due to name collisions. Examples
that could be complicated include BitcoinDark, Litedoge, and other names
that base on existing coins. I think the ability to differentiate
between test networks is also useful.
Could certainly just use the genesis hash as network ID, that would
work. Bit long, but suspect 64 bytes isn't the end of the world! I'll
see if any more responses come in then raise a BIP for using genesis
hash as an alternative to short names.
