eamonn: on TCG...
I don't think so. I think the industry has majorly miscalculated the demand for this widget. Motivated by both fear and greed, technology providers are hoping this generates new sales for them. It ain't gonna. And as soon as they see it ain't, they'll pull the plug. Meanwhile, MSFT maneuvers behind the scenes to water down everything the TCG does until the entire movement drowns in its own irrelevance.
I have yet to see a compelling argument to the customer--especially the enterprise customer. The generic "better security" is far too vague and money is too tight for those who control the purse-strings to give the green light. Is there a single enterprise who is actually using this technology in anything other than minor test mode? Who? Where? Has Wave? Has Intel? Has IBM? Has anybody? Until you can point to some firm that is actually using TPMs on a major scale, this whole thing remains in the realm of the pipe dream. Sure, IT managers might drool over this stuff, but how many IT managers get to replace their entire PC inventory without some outside approval? No, eamonn, TCG will die. It will be a just death because Trusted Computing was designed for the providers' benefit not the customers'. And, as some guy once said, the customer is always right.
