That's great to hear Hugh.

Cutting off JTAG pins won't do the trick :-)
I don't know about the US market, but the Australian engineering industry
has notoriously long suffered from massive revenue losses because of
copying product in Asia.
One automotive client of mine once sent a small After Market product to a
Malaysian partner company (based on PIC).
Within SIX weeks a replica of the product was sent back, HW, SW _even_
the case was faithfully reproduced (as an exercise).

Slicon was regularly microprobed to steal the code.
If these people go through the trouble of microprobing, I don't think
partially
cut off pins will stop them :-)
(Providing the design is worth it of course).

Virtually all designs I've done dictated code security as paramount.
