Wave's products will work with DAA as well,some users may require DAA with a Trusted Third Party & some without. All TPM's though will require Key Migration Utilities. There may be some applications that require Attestation like NGSCB,Banking etc & some where you only may want/ need to use DAA.
'guv, it's a protocol that's part of the tpm 1.2 spec, if I'm reading it correctly. That would make it not complementary and not competitive, but integral to ANY TPM solution...
