The ethical implications of bypassing the ability of people to put "no
solicitor" signs on their doors aside, I think doing this via network
allocations has two problems:

1. You're going to totally hose the routing table.  Reducing the
   Internet into /24's is bad enough, I shudder to think of shifting to

2. It's a hack, and doesn't *really* do what people want.  It will
   require sysadmins and network administrators be more sophisticated in
   their analysis, better tools, and so on.  But in the end the
   information is still public, in the ARIN (or RIPE or APNIC) database.

There was a talk at the Ottowa Linux Symposium on IP Anonymity, even
with some software:

The idea here is to create a mesh of IP tunnels, using peer-to-peer
techniques.  If a largish ISP with non-congiguous space allocations, or
a small group of ISP's, were to set this up as a service for their
customers, I think that would be a better long-term solution.  It
wouldn't hose the routing table, and would be very, very difficult
indeed to determine the "real" origin of a packet.
