In 6.2, coming middle of next calendar year, the mechanism for launching 
interactive jobs has been rewritten.  With 6.1 and previous, an 
interactive job is started by submitting an rshd as a job and then 
forking an rsh to connect to it.  (Or rlogin or telnet or ssh.)  With 
6.2, starting an interactive job means that the shepherd will fork a 
shell with a PTY and connect back to the qrsh client, no rsh/rshd 
involved.  (With Grid Engine, the slave tasks for a parallel job are 
started via the interactive job mechanism.)

There are several important benefits to the new mechanism.  First, no 
more rlogin port limits.  Second, SGE certificate-based security will 
actually encrypt the communication streams of interactive jobs.  Third, 
no more worries about whether your rlogin/rsh/ssh binaries are "tightly 
integrated" with Grid Engine.  Fourth, you actually get a PTY.  Etc, 
etc, etc.  :)
