A key store chip could be useful for some applications. However note: you can't defend TCPA as being "good" vs Palladium "bad" (as you did by in an earlier post) by saying that TCPA only provides key storage. As Michel noted TCPA and Palladium both provide remote attestation and sealing, and it is this pair of functions which provides the DRM functionality. Therefore for DRM purposes TCPA and Palladium are both socially bad technologies.
