OK.  If we want to use an identification system like this one, then as a
matter of design:
1.  We should provide a place, probably in the Control Panel, where the
user lists "my accounts".  Sugar will then tag each of these accounts with
the user's public key, so that other users can see that they are all
aliases for a single user.
2.  We do not need to provide a way for users to merge the identities of
other users.  Identifying my accounts as belonging to me is my
(software's) responsibility, not yours.

That's great.  I look forward to Mission Control and improved
interoperability.
