This is interesting! What can be done about this? Change the e-mailadress
and the key? I don't see any way to prevent it.
If it becomes frequent some verifikation of the link person - key must be
added. Or is there any work around?
How does MS Passport (and similar services) work? Passport will not mind if
the e-mail address is used by several people? It's very common on the web
with services that just validates the e-mail address. And they seem to work
so far ...
