Dear Linus,
I have an idea that you can show in your YouTube video.
Personally I am a real fan of linux and I would really like it if you want to demonstrate this project. I came up with this idea when I saw your steam caching server and immediately thought why no part 2? This is the idea. You have access to a few gigabit network cards. What happens when you put these cards in bonding mode and the steam caching server runs on that server? will downloading go faster? Try to put two network cards in bonding mode on the Linux client. I recommend using bonding mode 0 (Round-Robin), which ensures that all traffic passes over 2 network cards. I'm curious if you put both the server and the client in bonding, the speed actually doubled
Some URL's to the bonding guide
Look at this post: Bonding on ubuntu to learn more about bonding on Ubuntu Linux
Sorry about my bad English
