Re: And P2P users will ramp up their VPNs Yes, it does, but, as I said in a previous post, you have two choices. If you're just using the VPN to simply hide your connection to the tracker and not actually handle the file transfers, then you still have to reveal your real IP on the tracker; otherwise, other clients can't find you. The other option is to run everything, including file transfers, through the VPN. That will hide your real IP, since only the VPN server would know what it is, but the bandwidth and server requirements for something like that on a usable scale would be enormous. Unless you're taking in a significant amount of money to spend on that, you won't keep it going for long. Not to mantion that such a VPN would be the biggest target on the planet. Not only would the entertainment industry want to take it out, but, if they could hack it instead, they could see the IP of every single connection in real time. That'd really be better than trying to take it offline.
There is a third option--to dynamically establish VPN connections between client computers that were sharing files. That would at least keep those transfers hidden from anyone running DPI, and the bandwidth requirements would work, since you don't need a central server to handle every single one. However, now you're talking about having every client running a VPN client/server setup that has to work out new connections automatically as you connect to and disconnect from other computers during a transfer. It can be done, but it still doesn't hide your IP from the tracker and anyone connected to it.
