They were nice devices, and since they came out of IBM Research rather than a
product division they had the chance to do it right rather than do it under
time and budget constraints.  The unfortunate thing with it was that most of
the market didn't want a programmable high-security processor, they wanted a
turnkey/fixed-function crypto box.  They added the CCA functionality via
software but never really got PKCS #11 working, which more or less killed it.
