The gap size problem does not arise = there since such a system has to have an extra database keeping track of = requests, so there is no added cost of storing the key coordinates used = by them. A scan is not needed the keys can be accessed at random = order.

Not if you have 100 accounts on 10 different = devices.

I meant for a merchant with = a server that is handing out hundreds of = addresses.
