It just dawned on me that you probably intended to skip the rsh if the rcp fails. Given that, this seems less confusing to me:

Code:
while read hostname
do
    if !  rcp $DEPLOY $hostname:/var/tmp/$TYPE
    then
        print "Could not remote copy to $hostname"
        continue
    fi

    if !  rsh $hostname "nice -n 39 ksh /var/tmp/$TYPE &"
    then
        print "Could not mount the NAS on $hostname"
    fi
done <hostfile

EDIT: Given Don's observation, (I use ssh/scp so wasn't aware of the rcp limitation) this may not behave as expected. Using scp and ssh would certainly be an advantage if it is possible to use them.

NAME
rcp -- remote file copy SYNOPSIS
rcp [-px] file1 file2 rcp [-px] [-r] file ... directory DESCRIPTION
Rcp copies files between machines. Each file or directory argument is either a remote file name of the form ``rname@rhost:path'', or a local file name (containing no `:' characters, or a `/' before any `:'s). -r If any of the source files are directories, rcp copies each subtree rooted at that name; in this case the destination must be a direc- tory. -p The -p option causes rcp to attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignor- ing the umask. By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file mod- ified by the umask(2) on the destination host is used. If path is not a full path name, it is interpreted relative to the login directory of the specified user ruser on rhost, or your current user name if no other remote user name is specified. A path on a remote host may be quoted (using , ", or ') so that the metacharacters are interpreted remotely. Rcp does not prompt for passwords; it performs remote execution via rsh(1), and requires the same authorization. Rcp handles third party copies, where neither source nor target files are on the current machine. SEE ALSO
cp(1), ftp(1), rsh(1), rlogin(1) HISTORY
The rcp command appeared in 4.2BSD. BUGS
Doesn't detect all cases where the target of a copy might be a file in cases where only a directory should be legal. Is confused by any output generated by commands in a .login, .profile, or .cshrc file on the remote host. The destination user and hostname may have to be specified as ``rhost.rname'' when the destination machine is running the 4.2BSD version of rcp.
