[BC] Black Box circuits

[Mike McCarthy]

Potting was and still is the only way to really protect unique circuits 
which might (or not) be patentable before the patent application is 
submitted.  If it's truly a breakthrough...like Bob's 8000 and 8100 circuit 
designs, then why let someone else beat you to the punch.

Not everything is patented or protected.  Look at Coke.  Only a few people 
in the world know the true mixing process and ingredients of the syrup.
