2b.....is it that much work?edit The TCG TSS works with MSCAPI keys... The TCG TSS could work with Java JDK keys... The TCG TSS could work with Apple applications as well...... Apple would need to do a bit of work & tweak the TCG TSS then Apple applications could use TPMs & TPM key services... Wave would have to do nothing or very little imo..... Doma.
