on my debian linux boxes, there's a helpful option in /etc/login.defs:

# Enable setting of ulimit, umask, and niceness from passwd gecos field.
#
QUOTAS_ENAB             no

manpage for login.defs says to go look at the passwd(5) manpage, but which
isn't very helpful. it says to add `ulimit=xxx' to the end of the comment
field, but neglects to mention the format. the only other info i could
find was for the bash builtin ulimit, which probably doesn't help
much. anyone know the format?

lshell is another good solution, it's a wrapper around the real shell
which can set limits for the user.
