This is something out of practical world that would have to be
considered obviously. OTOH it is the prefix originating site that
controls who and how will see the prefixes, not the
traffic source site. Having control over what and to whom you
advertise, you have the capability to "not being announced"
to the "clueless".

The LISP adventure is not as simple as "go from A to Z" - it
may end up today if the test network decides to disband with
no hurt to anyone. It may decide to go on and convert only
the sites willing, which is actually what happens right now -
giving benefits to users, and normal service for anyone else.
