 But what other problems are there with this idea?  Assuming that there were lots and lots
and lots of accounts, what performance implications are there to giving each their own DB
rather than making them all share?

CouchDB keeps each database in it's own file, so if you can spread the
files across disks (using symlinks for now) you should get better
performance with many databases. DB-per-user is a good pattern also
because it means you can let users replicate their entire account
locally, without worrying about filtering out extra data.
