WAVE has been very interested in the Mobile space since at least 2006. Here is SS on the subject:
So Trusted Computing, we’ve only talked about the PC space. We touched a little bit on Seagate and the peripheral space. But the Trusted Computing Group standards organization encompasses all devices: peripherals, storage, PCs and mobile devices. There’s a very active mobile working group that has a couple dozen members, all the major telephone companies, and the goal is to put interoperable credentials on PCs and cell phones. So I can check my email from my Blackberry against my corporate server without having to own a Blackberry server. Because the device should have an open platform for credentials that the IT department manages, not the cellular operator manages. And so this is very well underway. The specifications will get published this spring. We expect to see first devices this fall.
