I got fiber run to my neighborhood, and for a while, had a 1gb coax connection and a 1gb fiber connection. I used openmptcprouter to aggregate my connections through a droplet and I effectively had a 2 gigabit internet connection. I would have stuck with it, but having a datacenter IP for your home network really doesn’t work.

Except TCP is just a bad protocol to start with for tunnelling, because packetized data has to be delivered in-order, and head of line blocking messes up congestion control algorithms in the tunnelled data.
