Chameleon on Linux/FreeBSD - solution how
Chameleon is great solution but not avaible for Linux and FreeBSD :(
Hamachi on start was this same problem and dont want share own solution (source code)
So they prepared already compiled executable files (elf) for making connection for linux x86, x64 and FreeBSD
I hope this solution can also use VyprVPN (i know you want keep yours sultion in secret) so already compiled (ELF) files and also crypted could be solution.
Chameleon is available on Linux.
