Apparatus and systems, as well as methods and articles, may operate to intercept a first request to use a platform configuration register (PCR) directed to a first trusted platform module (TPM) port, a second request to use the PCR directed to the first TPM port, or both, and to re-direct the first and second requests to use the PCR to a second TPM port capable of accessing a first virtual static platform configuration register (VS-PCR) set and a second VS-PCR set.
