i want to register an account with a service and persist details about that account in a SQL DB

[joshlong]

the hope here is to have a user sign up thing where user meta-data can live. We might use something like the Spring Security stormpath integration, or, worst case, we could just store the bits in a SQL DB.

Stretch goal: this could be a 'sign in with facebook' style thing, instead, so that there's less for the client to do.
