I would be sceptical. Does this thing breaks open standards like OpenVPN? I would love an opensource implementation of <a href="http://www.goldenfrog.com/vyprvpn/chameleon" rel="nofollow">http://www.goldenfrog.com/vyprvpn/chameleon</a> which works in China and also prevents Deep Packet Inspection. And about VPN: VPNs can also be a single point of failure for trust. You are giving away trust on your current connection from your ISP to maybe Bitmask/LEAP and a VPN which they call service provider. I also wonder how you want to make the financial side of this working. Running VPNs is expensive. I hope you succeed but I would say: Do not trust any free VPN out there.
Encrypted E-Mail is not the problem, there already are packages that install gpg without any hassle. What must be solved is the problem of which keys to trust. The web of trust just doesn't work. Are there any concepts how to solve this with Bitmask?
So, this is a VPN client? I find it odd that it only supports Linux and Android, considering that these two platforms already have built in and fully functional VPN clients.
For secure communication we should leave email behind because there's still a lot of metadata when using email.<p>Bitmessage (<a href="https://bitmessage.org" rel="nofollow">https://bitmessage.org</a>) might prove to be a viable solution to the metadata problem.
