True, but it does seem to depend on there being a gdb server running on the target. Easy on the gp2x f100 thanks to usb networking, but I'd guess a little more difficult on the Wiz unless you have a developer unit which has serial and usb (and I don't think GPH ever got the gadget usbnet drivers working for the Wiz so everything would have to be done over slow serial until someone ported them).
