Hi Michael,

thanks for a clear answer.

As discussed earlier, having a push/pull agnostic protocol would be 
nice. (and probably feasible)
As stated earlier, I think that discovery and which node starts the 
bootstrap protocol (BRSKI) is very much installation/technology 
dependent, and should be done in another document.

My intention was to reduce the coding effort of the registrar by making 
1) and 2) as similar as can be hoped for;
while payload considerations are of secondary importance.
My hope being that a manufacturer will deliver a registrar box 
supporting both coap and http versions.

When the consensus is that adding coap is already such an extra effort 
that code sharing between http and coap versions does not alleviate the 
effort,
then any solution for coap that concentrates on payload reduction is 
fine by me.
