Currently only one project possible per AWS account.

Currently it's only possible to have one project per AWS account - an AWS account is treated as a 'database'. It would be useful to be able to take the database NAME from the backend settings, and use this to prefix all domains created in SimpleDB - effectively allowing multiple apps to be hosted in one AWS SimpleDB (subject to Amazon's own limits.)

Actually - rather than name, perhaps a DOMAIN_PREFIX would be better. Then you could have two backends, with two different consistency settings, but with the same DOMAIN_PREFIX (so they read and write the same domains).
