It sounds like their claims are a little inflated. Able to bypass deep packet inspection? Not likely, though their techniques may temporarily evade the pattern matching that leads to URL blocks.
If $ISP does not block #VPN, that might be a better option than #GreenTunnel.
(Don’t get me wrong. I’m glad someone is trying different techniques to evade ISP blocking & censorship. I just wonder whether they’ve over-estimated the benefit in comparison to other techniques such as using a VPN.)
