This is assuming that 'ISP1' has the capability to advertise the OP's
route in the first place.

What if ISP1 is simply a customer of another ISP, using PA space, and
just reselling connectivity?

Charles, you really need to find out what others have asked... can the
ISP1 advertise your block of space for you, or do they really mean that
they *can't* do BGP at all.
