although i run plan 9 on my laptop, i have inferno on a USB keyfob which i can plug into any random machine (windows, linux, ...) and get access to a relatively sane environment. i use it to connect back to plan 9 machines, or to data-bridge across uncooperative local networks. i'm using it now from a linux box to write this email.
I never really got email set up for Inferno, though I'd like to. Got any pointers?
