I managed to download it ok that time. I can't see why it wouldn't work. (I 
assume the 1k/1n network sets the frequency in astable mode?) And I suppose 
using a cap for phase compensation would work too. Putting a variable 
resistor in series (or in parallel) with the cap might give adjustable 
phase shift. You'll just have to try it out and see!
