Attached are the latest versions of my native C Art-Net externals. Version 0.9 has no new features, but the objects are now compatible with Windows. I haven't done extensive testing, so the objects should still be considered beta. Please don't use for any absolutely critical shows, although you should be fairly safe on the Mac side. Would love to hear from Windows users regarding stability and performance.
