Lahana doesn't implement secrecy because it wasn't a design requirement. It solves a different problem and uses Tor to do that, albeit in a manner associated with 24 hours and some ductape rather than years of NSA and DARPA funding. If you have any suggestions for implementing secrecy while maintaining the ease of use aspect I'd love to hear them. Heck, even documenting all the risks you see with it at the moment would be useful as it would help people make more informed decisions.
I've seen mixed reports about tor being blocked or possibly not, which is part of the reason for the VPN. Thanks for the feedback though and I agree that for many cases Tor is a better solution while it remains directly accessible, especially if secrecy is a requirement.
Not quite true.
While Tor can't be used for all traffic, there are Tor apps -- OnionBrowser works quite well; I just tried it.
