yip, this is one of the reasons that medical and other certified 
equipment (e.g. military, industrial, etc) is so expensive to start 
with: there's an expectation of long life and an understanding that this 
is reflected in either the up-front cost or ongoing support / 
maintenance costs.  For the bulk-produced consumer-oriented product 
market, people are not prepared to pay and in any event it's usually 
cheaper to replace equipment than repair or maintain properly - and 
that's even if the product is still relevant.  Who still uses their USR 
Sportster?  Or even their 802.11b wifi access point?  In 10 years time, 
there will be

This is only part of a much larger issue relating to the speed of 
technical innovation and separately, consumerism.

What's relevant to the IETF is that it needs to make sound technical 
recommendations about the usability and appropriateness of standards. 
If organisations choose not to keep supporting some or all of their 
product lines, this shouldn't impact the IETF's ability to do its job.
