I agree with John's analysis of the constraints here. It may be possible to get the ISPs to move on the expectation that if they do nothing government coertion will follow. The caveat here being that the pressure the vendors are most likely to be responsive to would be from the US and it is not likely that the ISPs would become concerned about iminent regulatory changes from an outgoing administration, particularly since uniquely in recent history there is no expectation that a sitting President or Vice President will be on the ballot in 2008.
The ISPs face costs from bots on their nets, so there is a direct cost benefit. I don't think that the game of charging to eliminate caps would be viable for devices other than a cable/dsl modem rented from the ISP. That approach would introduce a harmful oppositional dynamic with the slashdot crowd. At present I would be happy to simply stop the problem getting worse by getting such measures introduced into legacy gateways. Turnover of the legacy base is somewhat harder. One thing that I have found personally is that the WiFi hardware currently supplied is poorly made and not fit for 24/7 operation. The devices overheat in hot weather, the WiFi service definitely degrades over time. I have a box full of deceased brand name routers. If my experience is representative we don't need to worry much about turnover. Otherwise what I would try to do to drive turnover would be to tie the security (bot capping) and future proofing (IPv6 transistion management) to a branding campaign that provides the user with a tangible direct benefit, vis peer-to-peer video conferencing 'just works' and administration issues 'just work'. We agree at the requirements level here: peer to peer video conferencing must work seamlessly. The difference is that I am prepared to require the applications to make adjustments to allow for the deployment of NAT while you appear to be insisting on a particular means of achieving that requirement. > -----Original Message----- > From: John C Klensin [mailto:[EMAIL PROTECTED] > Sent: Wednesday, March 07, 2007 9:09 AM > To: [EMAIL PROTECTED] > Cc: ietf@ietf.org > Subject: RE: NATs as firewalls > > (off list) > > --On Tuesday, 06 March, 2007 15:46 -0800 Tony Hain > <[EMAIL PROTECTED]> wrote: > > > While I agree with Brian that the enterprise draft will be > difficult, > > I also believe the SOHO one will be virtually impossible to get > > agreement over. > > I agree, although I think we might disagree a bit about the > reasons.
