This is what I have done on the screen server to achieve dynamic title.

in .bashrc :

PROMPT_COMMAND='if [ $TERM = "screen" ]; then printf
"\033k${HOSTNAME%%.*}\033\\" ; fi'

in .ssh/config :
# this won't work unless your screen server has openssh 5.1 or above
host *
  PermitLocalCommand   yes
  LocalCommand /path/to/ %n

Why would you tie this to your ssh command at all?

I have a postcmd in my shell like this (this is tcsh):

alias postcmd   'printf "\033%s%s %s %s\033\\" "k" "\!#:0" "\!#:$" "[$HOST]"'

What this means is: give me the first and last bits of any command I type in my shelltitle (you'll find those are the important ones).

which gives me: ssh address@hidden [] when I ssh into systems that do NOT have a similar csh prompt.

If I ssh into another system that has the same shell setup, I get:

usr/local/bin/irc [] as my title

This requires no special ssh privileges, works with ANY command, and works even if you ssh from system a --> b --> c.
