The quoting you need has nothing to do with it being backgrounded - it will
be the same backgrounded or not.
In general, the command passed with su is handed to the shell of the user.
That shell will be parsing the command afresh, so everything in it must
reach it intact, and so you usually want single quotes around the command:
su - nobody -c 'command here'
or
su - nobody -c 'command here' &

discovering once again how widespread BLINK was on the web.
