The incantation is

  compctl -s '`users`' -x 'n[1,@]' -k hosts -- ytalk

or something such (whatever array name you've used for the hosts).
This is the canonical use for the 'n[...]' completion, so here's a
patch adding this example to the manual page.  (You need yodl for this
to get through to the installable manual page.)  Hope this doesn't
clash with other manual patches this time.
