[tex-live] Updating packages over the internet a la MiKTeX

[Karl Berry]

    I cannot agree to include on DVD something not available for most
    users having only CD ROM.

Um, this is what happened last year.  It is not new.

And it's not about disc formats, it's about licensing.  The stuff that
got put in texmf-extra is not free-as-defined-by-FSF-and-DFSG.
