Why not ufsdump directly across the network to the remote tape drive?

>From the "ufsdump" manpage on solaris 7:

     f dump_file
               Dump file.  Use dump_file as the file to dump  to,
               instead  of  /dev/rmt/0. If dump_file is specified
               as -, dump to standard output.
               If  the  name  of  the  file  is   of   the   form
               machine:device,  the  dump is done from the speci-
               fied machine over the network using rmt(1M). Since
               ufsdump   is normally run by root, the name of the
               local machine must appear in the /.rhosts file  of
               the  remote  machine.  If the file is specified as
               user at machine:device,ufsdump  will attempt to  exe-
               cute  as the specified user on the remote machine.
               The specified user must have a .rhosts file on the
               remote  machine  that allows the user invoking the
               command from  the  local  machine  to  access  the
               remote machine.

(last time I did this, however, I just used SSH to pipe the output
 of ufsdump to stdout through ssh then redirected that into a 
 fifo buffer program and from there to DLT...)
