but in that case you are still using 'ssh' underneath of qrsh. Tight integration
is still not ensured then. You could try the SGE builtins, instead: (qconf -mconf)

qlogin_command               builtin
qlogin_daemon                builtin
rlogin_command               builtin
rlogin_daemon                builtin
rsh_command                  builtin
rsh_daemon                   builtin


cheers.
