projection questions

1) We'll be screening an experimental film (on film!) at a symposium, and
we got a query from the maker asking if we wanted a print balanced for a
xenon bulb or a tungsten bulb. I had never thought about this before, but
obviously the two types of projectors have different CT. Is it common for
prints to be made for both types of lamps? (I'd guess not...) When you
rent a print from FMC, Canyon or MOMA, what CT is it most likely to have?
(tungsten? something in between?) Assuming most prints are NOT balanced
for Xenon, what do venues that run Xenon due to needing the brightness
typically do? (just roll with it if the image is a bit too bluish???)

2) Our campus has a couple auditoriums I'd like to set up for 16mm
projector, but both have booths significantly higher than the screen, so
the projectors have to point down, resulting in unacceptable keystoning
with a std lens setup. I've been in theaters where the booth is high up.
How do they dxeal with the keystoning. I'm guessing it's some kind of
special optics that is hard to find and obscenely expensive... Is it
projector/lens specific? or is there some device that fits all?

thanks for any help...
