I'd been going on the assumption that the ID on the card would be the same as the Gamecode ID, limiting me to capital letters (which would become lower-case for Black), digits, and a handful of punctuation. If that's not actually the case, and lower-case letters can be used as distinct from upper-case, then that opens up many other possibilities.
I was rather unclear here (my fault); there was meant to an implied question. Can/should I treat the ID on the card as something different from the GAME code ID?
Oh, and Mecklenbeck is from Mecklenbeck Chess, where Pawns promote early. Mecklenbeck versions of Pawns promote when they reach the opponent's pawn row, rather than the back row.
