My thoughts:

a)      "One size fits all" solutions simply don't fit most organisations. Some 
e.g.:

a.        (e.g. "you support users connecting from home today", so obviously 
you can obviously scale to support the entire organisation doing the same at 
work, or

b.      "give each user their own VLAN" - yeah, we'll create 100,000 VLANs - 
imagine maintaining the FWs, routers, and how much more complex user 
provisioning and de-provisioning is going to be. What happens when users move 
between buildings? Telcos can make this happen, but telcos are in the 
networking business.

b)      Treating wireless users as "external" and then making them VPN in isn't 
new - that's been the thinking for 20 years. It was "start of the art" maybe in 
2000, but it's not now

c)       I know Microsoft was arguing for the "hard core" and "soft shell" 
since circa 2006 or so - so even that's now new. However I disagree that there 
should be one boundary (around the data centre) and we ignore everything else. 
Obviously Brian doesn't understand how large organisations (and I'm guessing 
other sizes as well - I don't have that much experience) work. Most banks (for 
example) are stuffed full of "knowledge workers" that depend on data being on 
their client PCs. For example I've seen reconciliations in a large 
institutional bank being run on over 2,000 excel spreadsheets due to lack of 
straight through processing between diverse systems. You can treat them as 
being "on the internet", but that's too difficult to do in practise with 
granularity. If you make them VPN in, you end up giving them wide-open access 
anyway. So why not just use 802.1x to guard your physical (including WiFi) 
access? Surely 802.1x is easier and cheaper to deploy than catering for 
100,000+ VPN connections?

This looks like just another "magic bullet" - simple solution to a complex 
problem that only works in simple (i.e. small) environments.

Cheers
Ken
