My focus is primarily related to providing a stable NFS file server though I do dabble in other things from time to time (as we have several hundred Linux machines around the school, and things occasionally go wrong).
I have, from time to time, patches against the latest kernels. You can find them at http://neilb.web.cse.unsw.edu.au/patches/
Specific projects include:
