      How would my 12 foot paraclips work for this exercise?

The moon is roughly 360,000 to 400,000 km away. By comparison, AO-40 had a 
apogee of about 60,000km. At 2.4Ghz, that's about 16db difference each way. 
Put AO-40 at the moon, and if I'm doing this right, you'd need about 32 
times the ground station antenna both coming and going to get with a few db. 
I'm gonna need a bigger rotor for sure! I'm sure smarter folks will check my 
math....

what would a sample average link budget be?

As far as I can recall we are pursuing both Eagle and the P4 opportunity 
equally, concentrating on common elements until the details are ironed 
out. Neither has been identified as a primary or secondary objective.
I agree a package on a lunar orbiter would be neat, but also that it is 
not the best use of what volunteers we have. We need more folks to step up 
to do things, AND we need to make better use of them when they do.

Wouldn't it be fun to have a transponder on this! ;-)
Fun yes, but dare I say it, a waste of precious Volunteer resources.
All lunar orbits are inherently unstable and will impact after a couple 
of years. The link budget requirements would not attract a mass user 
base.
I suspect the number of Technically Capable volunteers is already being 
thinly stretched in trying to provide both the primary objective Phase-IV 
Lite (funded by Federal Government dollars) and the secondary objective 
the Eagle HEO.
