They say all the ATOC cards [or is it phones] are going to be compatible
with each other, but I wouldn't take bets on it.

Being technically compatible and using the same stored
value may not be the same thing :-(

That's a whole new can of worms, but are you suggesting one smartcard
could have the stored value from dozens of different TOCs upon it (and
debit the right one at various stages in a journey) rather than have one
set of "bank of ATOC" money on it?
