A true VPN client which redirects all your data regardless of which program sent is is going to be tricky, since it requires a bunch of hooks into thenetwork stack of your operating system to tap into and redirect the communications.
If you are looking for secure communication between your own program and its counterpart on another computer then things will be a lot easier -- there is sourcecode in the code archives that can show you how to do data encryption, and there are also some SSL modules available for Blitzmax (IIRC Brucey made one)
