Hello, I have just released D/FW 0.16. Although gdb still does not work very well, D/FW now can program all variants of msp430, (original msp430, CPUXv1, CPUXv2) and Chipcon's Low power RF chips (CC1111/2511).
USB interface is now recognized as /dev/ttyusbmodem by MacOSX, and /dev/ttyACMx by Linux. (I have not actually tested on Linux, though.) And it became much easier to change USB VID/PID, since host side programs do not need to keep those IDs. http://homepage.mac.com/skimu/msp430/dfw/ -- Shigenobu Kimura
