I can find no end of Bosch LH 2.2 or 2.4 injections boxes. They're all over the freakin' place. Volvos, VWs, all of 'em! I've got two extra ones at home...

I would say unlikely. Usually what kills the FI boxes is unreliable power, like from a dying alternator or, as you mentioned, from jumping from another car. I must say, in seven years of owning a car, I've only been jumped once... it really shouldn't be a regular occurance... Extreme temperature will also kill the box.... Anyway, there's nothing you can really do to protect it that I'm aware - don't do anything "electrically stupid," and keep in mind they do die eventually - it's basic electronics and does have a service life. -Justin
