Rusty,
Here are a copuple of links I got with a quick google search.

How soon are one of you guys going to try this stuff. I'm going to be
puttting coolant in pretty soon.
Also, there is NPG, NPG+ (which apparently has some ethylene glycol in
it), and NPG-R which is lower viscosity but needs to be changed once per
year. They are all $25-$26 per gal.

It works out that a volume of NPG+ is only 17% less efficient than the
same volume of 50/50. Once hot, the vescosity is not an issue, being
only slightly more viscous than water (no system change usually
necessary).
>From the reports I've seen, it has to be true that there isn't a huge
difference in cooling performance. Ken Welter has already stated that
he's changed back and forth a couple time, and didn't see any real
diff in temps. Loads of folks with RX-7's use it, and also don't
report any dire consequences. At the same time, I'm not sure there
are global cooling improvements to be made either. I believe the benefit of being able to run pressure less, coupled with
higher boiling point makes it worth trying for me. Now if I can just
find some. Have you found any good online sources? Most of my normal
places don't carry it. Cheers,
Rusty (engine repair status- one week down, and going nowhere fast)
