Well, it mostly worked. After starting in an area with no scenery, it took a couple of minutes waiting before the appropriate airport came down, and FlightGear could be restarted properly. Flying the C172, terrasync mostly kept up, but in both my tests (one in the bay area, one in the relatively sparser UK) managed to miss one tile. I may be mistaken, but it appears to download a whole 1x1 degree area at once in alphabetical order, and there were times when nothing was coming down, so I think that if the order of the tile download within a 1x1 chunk was optimised to get the closest first, and if downloading was continued almost continuously based on position and heading, then I'm quite sure it could be made to keep up no problem. Very impressive stuff anyway.
