Remote emacspeak

I would be interested to know whether anybody other than Raman on this
list has managed to get emacspeak running remotely.  I have tried,
with help of a couple of friends who know UNIX better than I, and have
failed.  The machines can rsh to each other and the remote-tcl works,
but when I execute the change according to Raman:

set the environment variable DTK_TCL to the complete pathname of the script
# remote-tcl.

I get the error "process speaker not running".

Any suggestions?  Thanks.
