Get Xbox Media Center on your PC

So last year a semi-legal, err, illegal hack for the Xbox called Xbox Media Center came out that let you use your game console to look at digital photos, play audio and video files, and stream stuff off of a PC over a home network. Now, for some reason, Xbox Media Center has been ported to the PC. There are already a few other applications out there for turning a PC into an digital entertainment hub, but Matt from PVRblog thinks this might be the first time a program has migrated from a console to a PC, rather than the other way around.
