Your understanding of the GPL is wrong on many counts.
First, distributions are not subject to the GPL, programs are. Not all
of the packages in a distribution contain programs released under the
GPL. TeX, X, and Perl are good examples of major non-GPL packages.
Second, the use of GPL code in a _program_ makes that specific program a
derivative work, and any distribution of the result must be under the
GPL. The "derivative effect" does not impact the license of unrelated
programs in a distribution.
There is nothing in the GPL which requires any specific distribution
mechanism, or any specific price. The GPL states that any sale of a
binary copy must include a transferable offer to provide the source code
That said, Scyld is committed to providing an open source infrastructure
for high performance computing. If you price the bandwidth costs for
high quality co-lo service, you'll see that a low-cost CD-ROM is the most
economical way to provide a basic distribution.
