Sure. The question is really whether its "market share" would be enough to justify the effort. > - As IPv6-enablement is generalized, less and less traffic will be in IPv4. > Thus, each IPv4 address will become sharable among more and more customers. If an average IPv4 user is consuming 200 ports (or whatever value you prefer to assume) with their favourite p2p app, that is what sets the number of IPv4 users per shared address. It's the number of simultaneous ports, not the amount of traffic, that counts.
