Is anyone interested in doing this?
This feature seems like it might be almost there, so IMO it would seem
like a shame to release 24.4 without ever testing this in the wild.

I think that is a potential show-stopper. 
Perhaps archives could also provide keys for download in a standard location.
The first time you connect to a given archive, Emacs could offer to
download and import the key (with a suitable warning). Or is this crazy?
