That's a good opportunity to promote the suggestion again, I had about
one year ago. It was about adding an option to make downgrades less
attractive, see

  http://tracker.labix.org/issue35

The idea was to let the user specify a minimal priority difference
between the less recent version and the currently installed version that
is required to downgrade a package.

Leaving this option at a default value of 0 wouldn't change the current
behavior, setting it to positive values would allow some high priority
channels to downgrade packages from low priority channels if a certain
priority difference is exceeded. It would also allow per package
overriding of that behaviour.

I've also suggested an implementation which, however, seems to have been
incomplete. (It didn't cover all situations where priorities are used.)
Anyway maybe it could be useful as a suggestion.

Cheers,
