This is an interesting assertion. I thought the majority of
announced prefixes was due to folks punching holes in their registry
allocated blocks in order to do traffic engineering of one form of
another (multi-homing being a form of traffic engineering).
Can you point at the data which backs up your assertion (I'm not
disputing it, just a curious)?
