I won't claim to have thought of it before Andy did, but I did think it
up independently.  (But can't prove it, and didn't try to patent it
since I didn't think it was patentable.)

The real test of the validity of a patent is in court.  (But sometimes
the threat of a suit is enough, since even if you win it might cost
you more that settling out of court.)

Does anybody have proof of having or using this idea before Andy's
patent?
