Psssst - come over here in the corner while I whisper in your ear about
companies like Verisign. That WOULD solve the problem. It would also
violate the Open Source concept of Fedora upsetting the purists.
If you download initially from Fedora then you either trust the connection
today or you do not. And some mechanism needs to be invented that can
declare "trust old key for items dated older than XXX. After that trust
only this new key until YYY, after which you will need an even newer key."
That's probably the infrastructure improvements they mumbled about in
their status reports.
