Not sure about the hole compiling thing, but, I do know that it works alot faster than it will on vmware as I have tried both. As far as serial, soundcard, usb etc, support, it seems that it is lacking, but, just to have something to mess around with, wich only takes like 10 seconds to boot I may add is fun at least. It is really easy to get going to, so, that's a plus. All it takes is writing a little config file for it, unzipping the immage that it downloads for you and there ya go, as simple as that. As I said, the console that it uses is really accessible with jaws, so that's why I even messed with it.
