Your comments above imply that you know something about the security of 
medibuntu. If you know of a vulnerability in there systems or processes 
and do not report it to them you are doing a disservice to the 
community. I certainly hope this is not the case?

I agree with the other points regarding unsigned warnings and 
repositories etc.
