It doesn't work for me. The aim seems to be to extract the X
server's host name from the output of the who am i command,
but that doesn't give very useful info on my system. I see
more chance for success when analyzing the SSH_CLIENT
variable that is left behind by ssh. It contains the client's
IP address, which could be grafted into the DISPLAY variable.
I'm not a shell script guru, but I could try to put something
together.

Cheers
Stefan
