No way in hell I'm convincing them to install tailscale or similar on their TV / router.
If I used their (Hetzner) servers in the EU it's still be 20TB, but I prefer having the server 10 miles from my house.
Plenty fine with that pricing since I also use it to un-CGNAT services on my home server (I'd run this through Tunnels if it was significant)
Generally ~22GB 4k hdr muxes or ~8gb 1080p.
