More information: imagine an app which processes orders for concert
tickets via email.  The app connects to a server via POP or IMAP,
downloads orders, and then deletes them from the server.  There aren't
thousands of users simultaneously accessing and searching their mail,
but rather only one account (orders at example.com) but thousands of
emails per second.

Ideally, it could be cloud hosted so that instances could be launched
before tickets go on sale.  Instances can be shut down after the rush.
