Interesting concept! However, there were some things that confused me. When you connect to one of the computers for the first time, it rewards you with more connection, but when you restart that computer it gives you even more. Every time I connected to a computer I would immediately restart it because otherwise I wouldn't have enough connection to reach the next computer. It might be better to make it so that restarting a computer and connecting to it for the first time have the same effects.
Also, rewinding, although interesting, isn't really useful since you can just walk back to a computer to restore your connection by restarting it.
