So in addition to specifying the current livecheck.url and livecheck.regex for extracting an available new version number, there should be new options where a port could specify a url for a page where that new version's checksums are published, and regexes for extracting them.

Do you also want to support signatures then?
Public keys are pretty long though, but they usually don't change.
