know imo MSFT's route....If it happens i would expect an announcement before TPM 1.2's ship. Application developers would need a little time to develop TPM compliant applications using the CSP...but not much as it's a relatively simple task for MSCAPI developers.
"Files encrypted by Document Manager, in older versions, used whatever TPM aware CSP that shipped with the PC. Today, Document Manager uses the Wave TCG Enabled CSP."
That Document Manager Today uses Wave's CSP on Intel Motherboards,where as in previous versions it used Infineon's CSP may be a good indicator of what Wintel already knows....
