Hi Martin,

I'm somewhat confused. DINRG is a _research_ group of the IRTF, so
it's not about standardization in the first place, whereas secdispatch
is an IETF activity. So the question is what you want to achieve in the 
end: Discussion of the general approach for further input on the concept
or just a documentation what you did?

If you are interested in getting this standardized, my impression is
that you should get input from IETF DNSOPS people whether your approach
is able to satisfy the most important operational characteristics as DNS 

Furthermore, if you want to go for standardization, the whole underlying 
DHT specification is missing and I'm not sure that your model is
compatible with RELOAD ( One
needs to also check that and probably come up with a
corresponding modification of RELOAD or a completely new DHT proposal.
