Ekr,

I somehow missed Jonathan's original question about this.  I'll support
making this registry broad-based as long as we don't have to troubleshoot
it a lot from the security side.  Essentially this is going to be
an IANA space for SDP-folk determined names of the algorithms
from RFCs 3280 and 4055 (and later, any RFCs which update 4055).

The reason I don't want to use the broad registry if it entails
debugging is that it's not very likely to be in the consciousness of 
future security developers, not being integrated into a reference
security RFC, and there's not much precedent (if any) for using
the same registry for multiple protocols.
