I believe its already happening!! All be it on a small scale (to start with).
The German Government is supposed to be changing over to Suse Linux and the British Government is supposed to be conducting a feasibility study on Linux as well.
If both Governments decide on a change of O/s / Apps ... That will make a BIG dent in M$ coffers....
And like you said Anarchic .... more & more People ARE getting pissed off with M$ control tactics, Perhaps if they find Linux a bit too Geeky they might have a looky our way. :-D
