I mentioned this on the devel list earlier this week.  All that is
required is to pgp sign the packages file.  This could be done in a
separate file to keep backward compatability.  The problem is that this
would de-automate the process since someone has to sign the file.  Perhaps
we could only sign the stable tree since that may be done by hand and
users expect a little more from that tree anyway.  You are correct in that
there are breaks in the path.  Debian guarantees developer to master, but
not original to developer or mirror to user.  We would simply be fixing
one more bad link in a weak chain though.  True end to end authentication
can't be done with debian's model in my opinion, but that's no excuse not 
to fix the problems we can.

Thanks for paying attention to my rambling,
