Saw in the new BRAIN that problem solvers is making a bolt on adapter that slides over the Shimano centerlok splines and bolts down allowing the mounting of std. 6-bolt IS rotors. This will let Hayes/Hopes/Magura brakes be mounted on Saint/XTR/XT/LX/Hone hubs. One more incompatibility issue solved. Between this and the fact that Shimano will be offering rapid-fire shifters for XT/Saint in '05 and a few more Saint rear hub options, is making Shimano very inter-compatible again.
