Yes, I've tried VCarve, Cut3D, and the Shopbot program -- all work fine, at least for simple toolpaths. The tablet only has an Intel Atom processor, though, so I will probably want to generate G-CODE for complex toolpaths on something more powerful, then copy the file over. I've tried using 3D printer software on a different Atom2-based netbook, and it took forever to turn STL files into GCODE.
One problem, though, is that the tablet only has one USB port, so I can't connect both the Handibot and a USB mouse (recommended for VCarve -- my fingers aren't quite pointy enough to use the touchscreen). I've got a multi-headed USB cables with a built-in hub at work, so I'll bring it home and try using that this weekend.
