Hi Robert and Olaf, I've successfully converted WM_TOUCH to TUIO and made multi-touch framework integrated with OSG a few days ago. To my knowledge, WM_TOUCH can never work under Windows XP or lower versions no matter we define the macros or not. The Windows SDK itself seems to use '#if WIN_VER...' to disable multi-touch features under WIndows XP, too. So maybe we can only make use of some other third-party libraries if we want to have the compatibility on all Windows platforms. In my opinion, TUIO should be a good choice, with which we can also enable multi-touch inputs from phones, iPads and Kinects. I'd like to submit it as a plugin later.
