I suppose, but computing is also full of ideas that keep being reinvented, then the reinventors rediscover why they're bad ideas. There's been no shortage of e-postage proposals in the past. Anyone who was serious about it would, I hope, start with at least a cursory search of the on-line literature to understand what the previous ones involved, and why none of them ever went anywhere.
