Looks like this could take quite a while to process.
I would rather use a given deafult list of hosts.

Here is the solution with the zsh setup at our site:

	hosts="" # make hosts an empty list
	if [[ -f ~/.zshhosts ]]; then
	  # read in host list from ~/.zshhosts
	  hosts=$(< ~/.zshhosts)
	  set -A hosts ${(f)hosts}
	else
	  # set the default host list
	  hosts=(erdos euler gauss leibniz pascal)

	compctl -k hosts -x 'p[2,-1]' -l '' -- rsh ssh
	compctl -k hosts -x 'c[-1,-l]' -u -- rlogin

Comments?
