This is not the way I see it. Paying for DFZ slots is embedded in "cost
of doing business" for large / T1 ISPs, and in the recurring charges
they charge to smaller ISPs or customers. If there was a monetary value,
it would be relatively easy to collect a fee based on the number of
prefixes announced upstream. I do not see that happening.

It's all about money. The collective cost of announcing a prefix in the
DFZ is less than the collective cost of having a complex and impossible
to troubleshoot multihoming mechanism based on PA. As long as a DFZ slot
does not cost $100 or $1000 a month, organizations will not go for a
more complex mechanism. We are several orders of magnitude below the
cost threshold.

As of ID/LOC schemes, there is this myth that the table is small but in
practice large environments will have to maintain a very large ID/LOC
map which brings us back to the size of the DFZ again.

Michel.
