I've never heard of anyone doing this in any ecommerce system before, but 
it should be a Simple Matter of Programming. :)

Perhaps something to be concerned about is that GnuPG expects to import 
keys to a keyring and keep them around forever, and I don't know how well 
it does with thousands or tens of thousands of keys. I guess you could 
remove the key from the keyring right after encrypting, if the large 
number of keys became a problem.

Although I have to wonder if an ecommerce site would get very many orders 
from customers providing their PGP public key, so maybe the keyring would 
never get very big after all. :)
