Now forgive me if I'm wrong but isn't this like the Chrome extension Hola, where you route your connection through peers on the network? If so what is to stop some using Myst to download CP and that being routed through my IP and therefore linking it to me?

I can see why decentralised VPN seems attractive as you don't have to worry about your centralised VPN provider keeping logs and handing them over to authorities but for me I don't want other peoples traffic routed through my IP. Instead of the authorities going to the VPN provider and demanding logs they are going to come to my door and blame me.
