I'd be happy to work with someone who can implement a solution for the
package side. The important thing to keep in mind is that packages
are built automatically on many distributed machines. Any solution
for signing packages would therefore need to also be automated,
e.g. signing them automatically when the packages are pulled back from
the build client to server.
