how to install from remote tape drive connected locally

env:    sp2, 4.1.4, 8mm tape (on control wrkst)
.desc:
The customer has a third party application that he needs to install 
on a node.  The application assumes that the drive is local.  The 
tape drive is located on the control workstation.  How can you "mount" 
the remote tape device locally? 
.act:
You can connect a remote tape drive locally by "tricking" the system
using a local pipe.  The following steps were tested and seem to 
provide the functionality needed for this specific case:
.machine_a has is where the software needs to be installed
machine_b has the tape drive
.this procdure assumes that the setup program uses the following 
syntax:  setup %1,    where %1 is the tape drive {eg /dev/rmt0}.
.on machine_b, create a /.rhosts file
        cd /
        vi .rhosts
        add "machine_a user_id"
.on machine_a, run the following commands:
        rm -f /tmp/pipe
        mknod /tmp/pipe p
        rsh machine_b "dd of=/dev/rmt0 ibs=1024" \< /dev/null   \\
                > /tmp/pipe 2> /dev/null
        setup /tmp/pipe
