I am all for disucssion, but i would certainly think it is better to not 
work in solutions untill we have some clearer view of the dhcp-cga 
interaction is i.e. till CSI does the work on the analysis.
Once the analysis is done, we can then decide what solutions to persue. 
I mean, there is no hurry for having solutions for dhcp cga interaction, 
right? we can do things in the right order in this case imho
