About 20 people attend the gathering Tuesday. 
We started off by going over different scenario's in relationships between "parent" and child DNS Operator 
http://dl.dropbox.com/u/81151626/CDS%20Scenarios.pptx

Then followed lively discussion about alternatives and applicability in different situations including
	- child wants to roll KSK algorithm 
	- child does not want to expose backup KSK but advertise a DS for it
	- some child servers are lame which one should parent agent believe 
	- DNS operator transfer 

Among the issues discussed from the child side:
	how can a child cause faster uptake of CDS than the polling frequency 
	how can child learn why CDS has not been accepted 
	rules for child tools that are performing KSK rollover and what check to perform 

At the end there seemed to be rough consensus that CDS would work in large fraction of the usage cases 
but there are situations where other ways are needed to affect the change of the DS in parent. 
A number of the situations mentioned above will require next version of the document to include additional
text explaining how/if CDS applies in each situation. 

There was some skepticism about the uptake of CDS by certain communities. 

thanks everyone that participated in the constructive discussions
