I agree.  I believe the Moon is a job for the microwave 
bands.  Antenna gain on both ends is easier to produce (for a fixed 
dish/array, the Moon end will be gain limited by the need to have the 
beam cover for the varying position of the Earth due to libration).

Comeing up with a method to align the antenna initially will be an 
interesting challenge.  That will have to be automated, even if it's 
a one off process.
