It's a glitzie but incomplete answer, suitable, however, for most US 
interests.  The EGNOS system is frought with politics and infighting and 
like Galileo, may never be completes.  OR, it might work better than 
we've anticipated.

FWIW, WAAS was not originally an FAA plan, but was subsumed into the 
Agency for funding purposes.  There are a lot more players in WAAS than 
FAA.  LAAS, on the other hand, is primarily FAA.
