The more I think about this, I am beginning to lean towards just leaving 
this at the moment.  I think we should wait for some actual usage of the 
signing system before we can decide exactly what to do here.   Once a 
workflow is figured out for when a distribution starts using this 
signing system, we will know when the repo db is being signed (in a 
central location, on the developers computer and then uploaded, etc) and 
by what key (repo master key, developers key) and then we can see where 
improvements can be made.

So lets just skip that TODO item for now.
