There's no doubt that if you can persuade all the upstream ISPs to do
the right thing, and persuade all the local downstream ISPs to do the
right thing, the IX-based addressing model can help a lot (and can simply
use PA space as if it was PI). But I don't think the economic forces involved
will exercise the required persuasion.
