American ISPs could do this, it would just be marketed differently.

Just remove all speed restrictions to traffic within their own network.

If only traffic leaving your network is a problem for scaling, then don't restrict internal traffic. The P2P clients would naturally favor those local faster peers, and if enough larger ISPs did this, then the P2P clients would be explicitly changed to favor local peers.

The problem is my speed limit is determined by my modem edge device's sync. And that's determined by my snr from the node. I don't think its possible to open up more speed for me if I'm already on the highest tier of the service. I guess for people who aren't, this is an option. Its not like I'm on a 1gbps line and they're only giving me so much internet. I'm on the max the last mile technology can afford.

I don't really know the numbers, but perhaps the majority of the customers for your ISP are not like you but have the entry level plan. And perhaps the majority of their p2p bandwidth comes from that large contingent of entry level users. This is not obviously true since p2p users are probably more likely to have the upgraded speeds, but it might be true. In that case, it might be that allows entry-level users to have faster access to internal nodes might reduce the overall traffic outside of the ISP.

So the ISP could benefit, and users could benefit and the ISP doesn't need to make any statement for or against p2p clients.

I do remember some ISPs doing web caching way back, but I think when the DMCA was passed they dropped this service for most cases since the liability on copyright infringement outweighed whatever benefits it gave them and their customers.
