OK, in "Re: [RRG] Mobility, update rates & charging per update" 2008-03-17: http://psg.com/lists/rrg/2008/msg00833.html Joel wrote: One small aspect that I think I am seeing here is the same words ("incrementally deployable") being used to describe two different concepts. I may be confused, but it looks to me like: (1) Deployable incrementally without disruption: This means that a portion of the net (host, site ISP, whatever) can deploy the system without losing capability or connectivity. A flag day is not necessary in order to get the system operational. (2) Deployment incremental incentives: This sounds like what Robin is asking for, and is related to a bunch of work I have seen from folks like Dr. Odlyzko on the economic incentives that are needed to drive deployment. It includes analysis of issues like when do folks need positive return on new technologies to cause them to deploy. They are both valid concerns. But I think they are two different dimensions. and you initially wrote, in "RE: [RRG] Hosts, DFZ, purity & incremental deployment" (2008-03-17): I would consider anything that could be rolled out one host at a time without breaking anything as being the maximal amount of incremental deployability. This initial statement of yours seems to be compatible with Joel's (1), but not to mention the more restrictive criteria in (2), which is much closer to the way I use the term "incrementally deployable". So I am unclear to what extent you embrace Joel's (2), and I am not sure to what extent you embrace my even more restrictive, and I think useful, definition in: http://psg.com/lists/rrg/2008/msg00846.html with the last word "yes" changed to a "no". I think we need an agreed understanding of "incrementally deployable" since it is one of the requirements in the RRG Design Goals: http://tools.ietf.org/html/draft-irtf-rrg-design-goals-01 - Robin -- to unsubscribe send a message to [EMAIL PROTECTED] with the word 'unsubscribe' in a single line as the message text body. archive: <http://psg.com/lists/rrg/> & ftp://psg.com/pub/lists/rrg
