Do your microwave folks know of any good RF absorber material for 
cheap?  We've been thinking here of fabbing our own due to the crazy 
prices of commercial material.

Also, do they know of any antennas that are cheap and come with not just 
gain, but also radiation splatter shielding?  ie: keep the radiation 
focused only where it's supposed to go, with massive F/B and F/Side ratios?

These are the present problems plaguing us here in the Puget Sound.  
Perhaps your experts can help.

As far as the 72km link goes, as long as you've got the height, you can 
do it no problem.  The curvature of the earth becomes a significant 
issue at those distances though.
