I'm not very familiar with them, I only know the basics. My initial
reaction is definitely "over-engineering". What's the support like for
namespaces in the various processors?

I think that there is a good chance that most of the problems that you are
solving could be resolved by simply using URIs, however I have my doubts.
My gut instinct is telling me to leave namespaces until pingback 2.0 -
remember 99% of all files will simply define xml-rpc and one fallback :)
