It looks like they are trying to emulate onion routing, but on the regular Internet. At the very least, it turns your computer(s) into exit nodes for VPN use. They recommend 3 devices, but also of course you have to keep your router available. I can imagine this getting your IP blocked from some sites. Chances of you noticing might be slim, but it would be quite a pain if it did affect a site that you do visit. Also, the unspoken part: They are using your electricity as well. So hopefully whatever you get out of this pays enough for that as well.
