Some months ago I was wondering about this. Someone (Oleg, I think) talked about the "thriving ecosystem" of 3rd party addons sustained by FS2004/X. It would be interesting if 3rd parties started developing maps, airports, aeroplanes for CloD. Just Flight publish small airfields for £7 or £8 each, and I might be willing to pay for a photo-realistic Biggin or Hawkinge... (In fact I might fork out 50p for St Paul's cathedral. Grrr....) Also, we know that the sim can accomodate flight up to the edge atmosphere itself. Il2 Space Shuttle, anyone?
