in fact, one of the reaons i'm riding these threads so hard is that

that'd work fine (ya might want a resistor in series to limit the
current in the quick zap that happens while the plug passes thru....
but it would work fine

yields OFFSET
and (speaking strictly for myself) i've found offset to be invaluable
when interfacing to a wide range of external gadgets.

that's why i'm behind this one!
