You call it "the other issue" but it is the only issue.  They do not 
give a tinker's damn if they interfere with us (and I suspect they 
won't) but the ability to sell receivers with CRAP for front ends (in 
terms of dynamic range, IMD, etc.) making it cheaper to manufacture is 
severely hampered by the "licensed stations" in adjacent bands.  There 
will be regulatory relief sought for the "health and safety" etc. 
services provided by Galileo from those stinking pest hams who are 
simply obeying the law on their licensed systems.

I am still of the opinion that this system serves no useful purpose 
whatsoever except to say "us too".  It is a political impossibility to 
turn on SA now in my opinion but now there will be no need to at all.  I 
suspect a treaty guaranteeing no SA and no allowance for design and sale 
of jamming equipment would be a LOT cheaper than this system.
