I don't know, IANAL. Far be it for me to say whether it's looser or more
restrictive. I honestly don't know what constitutes a "customary
medium". It might be that you are right and on-line distribution is
enough. And I do agree with you that whether this medium is convenient
or not to the user is probably not relevant. But I wouldn't bet the farm
on what constitutes a customary medium.

I hesitate to summarize the GPL so much, given that we are trying to
figure out a relatively fine point of the license. If I was trying to
explain the GPL briefly to someone, I might say something similar to
what you said, but your definition loses the details; and it is the
details that we are talking about here.

I disagree with your summaries for (b) and (c) btw. If I wanted to make
them almost as short, I would say:

b) Be willing to give the sources for the cost of the media for 3 years.
c) If you got the binary under (b), then point to the third party that
gave you that offer.

Maybe so, but then it depends on whether a judge considers online
distribution of sources the same as accompanying the binary with the
sources under a customary medium (when what you got was a CD). He might
decide it's the same, but I wouldn't bet on that.

I'm sure you've seen a few arguments that you thought were technically
laughable go through in court.

Cheers,
Daniel.
