How much difference is there between one AS (the colo provider)
announcing a prefix and another AS (the customer) announcing it through
the first AS (the colo provider)?  If the space is ARIN assigned PI, it
isn't going to aggregate with the colo provider's space, so the prefix
will still be a separate announcement.  The only difference is the AS
path is one entry longer.
