Atmel has two choices.......Bundle Wave's ESC & CSP as ST Micro did.........OR...... Develop their own software from turn on to key management to CSP. The problem Atmel would face developing their own would be their ESC & CSP would only work with an NTRU TSS while Wave's works with an IBM/Infineon/NTRU TSS.This would set them at a disadvantage to ST Micro & NSM who would be offering Wave's ESC & CSP as well as other TPM manufacturers that chose NTRU's TSS & Wave's ESC & CSP.
I believe Atmel will Licence Wave's ESC & CSP as well as NSM....it's just a case of waiting for the announcements imo....... They will be two more sources of revenue & the PC OEM relationships thereafter using ETS will be further sources.......
