With nowadays technology we can accomplish distributed p2p network, where every user is treated equally and can access any address in the network.
The biggest problem was hosting a node. Non-geeky person wouldn't host TOR because it is too hard to set up, net-traffic generated by TOR was easily distinguishable from other.
Simply put, too much risk, too small reward.
Substratum's guys found the way to solve this.In theirs scheme hosting a node will be easy as pie and will give you economical benefits, small reward as a SUB token for hosting. SUBnode traffic will look the same as regular net-traffic.
Simply put, low risk, relatively big reward.
You will be able to enter sites hosted on the network, and more interestingly, you will also be able to visit any site from regular Internet. Example : Human in China queries SUBnode for facebook.com, SUBnode in US queries facebook's server and conveys the data to user in China. Now people behind Great Firewall will be able to see forbidden sites, using regular Internet connection, without Firewall noticing with minimal human-effort and additional economical profit.
Communication with team is clear, they are active in social-media. Beta testers started work, next version will be public. Also devs annouced open-sourcing code. They don't hurry and keep focus on delivering best possible product.
