Sounds great (Now having Sigma DP2m support, but unfortunately for me it doesn't apparently run on Windows.
Rawdeveloper (and RPP too) runs in virtualized OSX that runs in commercial VmWare (PC/Windows) w/ less effort or free Oracle VirtualBox (PC/Windows) w/ more effort... granted that, like Hackintosh (running OSX natively on PC), does not honor Apple'e EULA.
