That's already done.

This is possible but there's something weird going on with some people's 
rebuilds. Touching the files will cause a rebuild, so rebuilds need to take a 
'reasonable' amount of time. Shipping the binary data improves first-launch 
perceptions, but many applications do additional work on their first launch 
after an install, so it's not my top concern.

As I said in the bug, my concern is why the rebuild times are so bad for some 
people - it's purely a CPU / disk-bound operation, and for me and all people 
I've asked, it's around the ~60sec for debug, ~30sec for release times for a 
complete rebuild. 

(That time will be dramatically reduced if we get the taxiway data out of 
apt.dat in the future, since taxiways account for >80% of the lines in the 
file).

Regards,
James
