If you instead chose the *first* few hex digits of the *SHA-1* of the user's
public key, it'd match the beginning of the XO's default userIDs in the normal
activity sharing/chat mechanism, which may be useful if you're trying to sort
out network issues.

In the XMPP/Jabber backend, the account Sugar currently tries to create is the
hex SHA-1 of the public key, plus "@", plus the server name. In the
link-local ("Bonjour") backend, Sugar uses the first few hex digits of
the SHA-1 of the public key (I forget how many - I think it's 6 or 8?)
plus "@" and the XO's hostname (which defaults to xo-11-22-33 if the MAC
address is xx:xx:xx:11:22:33).
