Several new Casio keyboards can use their Internet Data Expansion System to import new sounds into these keyboards. I am considering the purchase of a Casio WK300 that has this feature but the software to download sound and install it only works with Windows. Has anyone had success using this softwre with Virtual PC or in some other way?

I couldn't even get it to work on a real pc.

Casio support stinks.
Which is too bad, because for a beginner, that WK-3500 or 3000 is fantastic sounding keyboard.
