as you might have dedicted, I did not do this.

In talk about other issues with Ole Tröan, he suggested RFC4620 "IPv6 Node 
Information Queries" as a potential mechanism that could be augmented for 
sharing all kinds of information between nodes. I just read this and it 
could be used, but I don't have a firm opinion yet exactly how it should 
be formatted, how to do indirection (if needed).

I feel we need to understand the deployment model better, we need to 
decide who should have access to what information (if we put it in DNS, 
should anyone on the Internet have access to the speed of the Internet 
connection and if it's metered or not? There are pros and cons with both 
making it secret or not).
