usb key email application?
I'm looking for an email application that is stored on a USB key. I would like to plug it into whatever pc I use (whether mine, or another) and access my email, with no installation. I want it to run on windows and linux and store my emails in the key if asked to.
It would be nice, if I was able to then "download" the archived emails from the key to my own (ark linux) pc when I got back from a trip.
Does anyone know of such an application? Am I dreaming of such an app?
