Infineon's TSS can only support TPM manufacturers that licence Infineon's TSS. If TPM manufacturers choose to use NTRU's TSS instead of Infineon's........that's tough as it leaves Infineon as an isolated stand alone TCG island(that also includes PC OEM's that use Infineon's TSS). If Infineon wanted their application software to be compliant across all TSS's then all they need do is licence Wave's CSP kit.......
