Just in from the RSSAC. We will add the questions asked of us to the appropriate Work Tracks. Although some of the, may naturally fit in Work Track 4, others may be overall questions to the Working Group. If you have any thoughts on responses, please do not hesitate to weigh in and we will start keeping track on a Google Doc. Jeffrey J.

In addition to its formal advice, the RSSAC raises the following questions for the wider community (including GNSO) to consider. These questions go beyond the specifics of operations of DNS, the IANA functions, and the root server system, to broader issues of the costs and benefits of aggressive expansion of the root zone: * Independent of expanding the commercial buoyancy of the DNS industry, how does the addition of many thousands of new gTLDs to the root zone make the Internet better for the people who use it, aside from the addition of IDNs for language and culture? * Using concepts from the disciplines of library and cognitive science, what number of TLDs results in their loss of memorability and significance? * Is adding a significantly large number of TLDs (e.g., more than 100,000) to the root zone, and presumably augmenting the business interests in the addressing system, a sustainable model for the DNS? At what point might this model fail. What next steps for naming system innovation are required, and when?
