various instances of external repositories
It is not possible to add more than one external repository per type (e.g. Google docs), whereas it is quite common for a user to have more than one google & google doc account (e.g. personal and professional use). I see no reason for this restriction.

Instances of external repositories are not user-based, but platform-based. E.g. user 1 cannot have YouTube and MediaMosa whereas user 2 has YouTube and Flickr. Likewise it's not possible to create an undefined number of instances per external repository and per user.
