in 2.0 kernels, at least, a certain group range could bind to privilidged
ports. i do not know (because i haven't looked) if this was removed for
2.2 or 2.4. if not, its worth looking at.

alternatively it could probably be coded into the kernel (make the uid 0
check actually a gid range check, ie gid < 12).
