portable

I need to exchange encrypted messages with another party. These would be in the form of email like communication (not instant chat). The solution needs to be portable (USB stick).

I've tried "Portable Thunderbird/Enigmail/Gnupg/Hotmail account" but it's just impossible to setup portable, countless meaningless error messages. Anyway, I would prefer something more straightforward.

Notes:

We won't know each others IP addresses.
Our computers will often be switched off.
Encryption would ideally be using a common password.

Is there a solution to this?
