What is wrong with getting all the developers to either buy a code
signing cert or a generating a self-signed cert and using that to sign
both the updates.rdf and the XPI when they build the XPI file?

That would make all these issues go away in a flash. I already sign my
XPI's and signing the updates.rdf wouldn't be so difficult.
