The output would be too noisy on a large network. Few weeks ago I ran 
something that would go like this:

   ( echo "Sun bxes with telnet";                 \
     nmap -n -P0 -iL list -p 23 -O -oG - |        \
     grep -Ei 'Host.+open.+(Solaris|SunOS)' |     \
     cut -d ' ' -f 2                              \
   ) | mail -s "Check those" unixadmins@...mple.com
