Does this comparator exist....
Has the usual two inputs, inverting and non-inverting, BUT it switches
when the DIFFERENCE between the two inputs is some reference value,
either fixed/built-in, or adjustable by an extra pin?
I know I could construct such a thing, but I'm looking for something
small, minimum pins, etc., i.e. a Joerg part ;-)

How about a TL431? 
If you want something faster, there's the MCP65R41T.

Nope. I would have to add stuff to make that work.
I need a comparator, with a couple of volts of common-mode range,
ideally with an adjustable difference between + and - inputs at the
switching point, but I can live with something fixed at between 300mV
and 500mV.
Seriously! A Joerg part ;-)

I love to cook with wine. Sometimes I even put it in the food.
