James,
My regular laptop is a home computer that sits behind a commerical
router most (not all) of the time. My Ubuntu machine is a generic
computer that could be taken to a coffee shop or more likely a bar, or it
may be plugged directly into a DSL or cable modem. I am writing up my
instructions on the assumption that the person following them is not a
computer expert.
