Sure. The question is really whether its "market share" would be enough to justify the effort.
But how can you know what the "market share" is? I mean, it's a trade-off between having a smaller sharing ratio and having better
end-to-end (perhaps), direct CPE-CPE communication ... I say let's give ISPs more solutions to avail, so they can adopt the solution that suits their needs.
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.
There was a thread on this list recently, which discussed a research on port reusage by applications: |> For example, BitTorrent established five hundreds of sessions while |> the port consumption was under a hundred in the first minute of the |> communication, because when BitTorrent initiates a downloading, it |> first uses the same source port to connect to the different |> destinations (destination IP and port) therefore one source port |> multiplexing different sessions. Skype is another example that uses |> one source port to multiplex different sessions thereby |saving source |> port consumptions on NAT. So I guess we have some reserves here as well.
