Why not borrow the general idea from Java and Android, and just incorporate  
DNS itself into header names.

com.courier-mta.MYSTUFF: whatever

I can use any header that starts with my domain name, for whatever I want.

No need to maintain a registration service of any kind. DNS is the  
registration service. If you own the domain name, use any header that starts  
with it.
