Please note that CNAMEs point to FQDNs wich have a class. This makes 
it messy both ways.

I am sure that this will call endless IETF discussions; and then a 
transition period. This is the same as the IDNA2003/2008 transition.
 From a user point of view 256 classes can be freely assigned. Until 
the IETF C/DNAME classlessness confusion is clarified, InterUsers 
classes will not support CNAMEs/DNAMEs. Other options (may) exist: 
they should be first discussed as per Moakapetris' last week 
presentation and ICANN/ICP-3, then tested, reported and discussed.

idem. This whole issue is to be considered in LISP and 
intertechnology context. The internet (and hence its governance) is to mature.

I can only repeat: IEN 48 had two motivations in succession:

1. to prove that Louis Pouzin's catenet concept could be extended 
globally (i.e. the internet). This is completed.
2. to prove that this global extension could extend to the Tymnet 
intertechnology.concept (the intertech). This is what we have to do.

The main resulting question for the Internet Governance is therefore 
how the WSIS concensus on an MS-IG will address this architectonical 
(politics, international, architectural, technical, societal) 
challenge. There are two possibilities: united or not united. United 
means that MS equal footing extends to end-users. Not united means 
that some consider end-users as consumers and restrict equal footing 
to Govs and TransNationalCorps with some of them being more equal than others.
