I see your point, but I'm not sure how to do it any other way. 
Switching between 2 proms, or a prom and a flash would be simple with
some gates, but if you're going to download stuff to it like from a
laptop I think it has to have a microcontroller of some kind.  Once the
program is done, it's not too difficult to program a bunch of chips and
send them to people.
