Hello List - I'm attempting to create a licensing mechanism for a bit
of software.  I would like to be able to use a unique and
non-modifiable identifier as part of the mechanism.

The CSRSI callable service and STSI instruction provide a variety of
hardware related identifiers.

CSRSI returns fields called si00pccacpid and si11v1cpcsequencecode.  These
appear directly related to PCCACPID (PCCA control block) and Sequence Code
(STSI basic machine configuration)..

Is there any preference to using one field over the other?  What are the
advantages and disadvantages of using each field?

Are there other fields (in same or other control blocks) that should be
used?

Please feel free to treat this as an open ended question related to
licensing mechanism and provided any related advice and tips based on
experience.

Thanks,
Sam
