Hrm. IPNetShare appears not to be the right tool. The free version does not come with support, and, as soon as I launched it, it told me that my trial period had expired and then quit So fuggetit, I think. Life's too short. Not to mention, woo, what a crappy clickthrough license.

I think I really want to accomplish this from the command line. If nothing else, turning this into a command-line recipe would allow people to google up the formula over, say, a cellphone's WAP browser and rekey it into a laptop -- IOW, I don't want people to have to have Internet access in order to GET Internet access.
