I don't know about other projects but it seems that most of them
failed (but one, http://code.google.com/soc/2008/minix/about.html ). I
was one of the two students chosen to develop a USB Stack for Minix
(as well as some drivers for mass storage, mice and other usb
devices). The two of us dropped out.
Best regards.

As Ben said, the storage driver project was the most successful. The
ARM port and the voting machine projects are still being actively
developed by VU students. The NDIS project is being proposed again
this year. The USB project is not, however, as it may be too large
even for "a tenacious student who thinks sleeping is a waste of
valuable coding time."
