Set a default route to the Win2k box with a higher cost (say, metric 2) 
than pppd brings the other route up at.

The routing should prefer whichever route has the lowest metric, all 
else being equal.

If you want to reply correctly to traffic *in* from both routes at once, 
or to load-balance (half the connections through each route, for 
example) that's also not too hard but does require a handful of 
iproute2 commands to make it go.
