You should be able to just change the protocol to udp, like "(echo > /dev/udp/$SERVER/$PORT)"
Great topic. I would add that you can use <br> for a new line.
Here's another one. I've been using it for years:
$ type my-ip
my-ip is aliased to `wget http://checkip.dyndns.org/ -O - -o /dev/null | cut -f7 -d"<" | cut -f2 -d">" '
Output would be:
Current IP Address: xxx.xxx.xxx.xxx
Nice... another option is to send a meeting invite for lunch from their computer... but this is a lot cooler.
