It seems people try to use this as a cheap way to provide DR and HA in one foul swoop. I've yet to see anyone succeed in doing HA/DR on the cheap (though that's not for want of people trying!) I guess I remain to be convinced there's a need for this sort of thing. But then I'm a purist at heart and don't like seein g people using one technology to do two different things that it wasn't really designed for in the first place. :) Pete "Controlling developers is like herding cats."
