+1 for SSL of packages.
A compromise would just be to run the entire mirror both http & https with a
self signed cert and leave the default http.
The packages that are coming from the ubuntu mirror are very important
especially since so many companies use ubuntu in production environments.
As for the whole self signed vs. signed by a company I don't really care and
I don't think many do either. People that modify the packages to use SSL
will know why and what they are doing. Those who don't will just default to
