No explanation.  I do this all the time.  Although I only use crafty vs crafty
or crafty vs
gnuchessx.  But it never fails for me.  You just have to be sure you use the -fh
and -fd
to set the hostname and the directory to run in.  Otherwise the program has to
be in your
home directory on the remote host, which is clumsy...  Ditto for -sh -sd for the
second host
and second directory...
