As I understand it, the plan is for Longhorn to provide the trusted applications environment, whereas the TPM as we know it today is strictly a keys management technology. Actually the TPM could become programmable in which case it's a different story, except that the host PC OS (Longhorn eg.) will remain as the host's trusted apps environment...local vs. network (Longhorn vs. programmable TPM)?
My sense is that ClearTrust and similiar software will eventually run on Longhorn as trusted apps, whereas today they are just security software running on Windows. I don't think ClearTrust is TPM software by today's definition, unless it can directly interface with a TPM.
