GPL law - Limits on distribution fees? When is something "distributed?"

The document linked below contains some thoughts on GPL law. These are notes on the law surrounding the GNU General Public License (GPL, GPLv2 and GPLv3), created by Richard Stallman.  This is not intended to be exhaustive, as it's only preliminary academic research into a topic I find interesting and important.  This document is not intended to be a statement of the law in any definitive, or even reliable, way. As academic notes, by a 2L law student, this document is subject to mistakes and omissions.
