It's going to be more expensive than you think, if you try to live in it the way you would in a regular apartment or house. The need for lightness in construction means there are compromises that you will have to work around.

I found Visible to be fast enough at 5mbps for most things. I hooked up a Wifi router to serve as a client for those cases where I wasn't tethering.

I think it is tougher when you try to work a remote job, since you basically do everything in the same small space. Eat cook work sleep read etc all in the same x square feet.
