Actually, my suggestion would be for those system users that are
associated with network daemons, to use a group to match the port they
open...i.e. apache assigned 80, ssh assigned 22, etc.  No real reason,
except to try to have SOME rhyme/reason to assignment - those that don't
do network stuff can be assigned somewhat arbitrarily.
