you might be better off appending an entry into the remote box's /etc/passwd file and then creating the home directory as required ...

a. create /etc/password and /etc/shadow strings for the user into temp files
Code:
vi /tmp/pass
vi /tmp/shad

b. transfer the temp files to remote host
Code:
cd /tmp
for remhost in `< /path/to/hostlist`
do
    tar cvfp - pass shad | ssh $remhost "cd /tmp; tar xvfp -"
done

c. append the strings and create home directory as required. put in the correct homedir path as required. please make sure to use ">>" or you'll clobber your files ...
Code:
for remhost in `< /path/to/hoslist`
do
    ssh $remhost "hostname; cat /tmp/pass >> /etc/passwd; cat /tmp/shad >> /etc/shadow; cd /home; mkdir -m 755 bpadm; chown bpadm bpadm; cd /tmp; rm pass shad"
done

the only catch here is your use of sudo ... you might want to put the commands i listed in item d in a script and then call sudo to run the script on the remote box ... assuming that you can put in the root password

the script ...
Code:
#! /usr/bin/ksh

[ -f /tmp/pass ] && cat /tmp/pass >> /etc/passwd
[ -f /tmp/shad ] && cat /tmp/shad >> /etc/shad
[ ! -d /home/bpadm ] && (cd /home; mkdir -m 755 bpadm; chown bpadm bpadm)
rm /tmp/pass /tmp/shad 2> /dev/null

exit 0

the job ...
Code:
for remhost in `< /path/to/hostlist`
do
    scp -p /tmp/script $remhost:/tmp/script
    ssh $remhost "hostname; sudo /tmp/script"
done

bup-fuse

bup-fuse(1)						      General Commands Manual						       bup-fuse(1)

NAME

       bup-fuse - mount a bup repository as a filesystem

SYNOPSIS

       bup fuse [-d] [-f] [-o] <mountpoint>

DESCRIPTION

       bup fuse opens a bup repository and exports it as a fuse(7) userspace filesystem.

       This feature is only available on systems (such as Linux) which support FUSE.

       WARNING: bup fuse is still experimental and does not enforce any file permissions! All files will be readable by all users.

       When you're done accessing the mounted fuse filesystem, you should unmount it with umount(8).

OPTIONS

       -d, --debug
	      run in the foreground and print FUSE debug information for each request.

       -f, --foreground
	      run in the foreground and exit only when the filesystem is unmounted.

       -o, --allow-other
	      permit other users to access the filesystem.  Necessary for exporting the filesystem via Samba, for example.

EXAMPLE

	      rm -rf /tmp/buptest
	      mkdir /tmp/buptest
	      sudo bup fuse -d /tmp/buptest
	      ls /tmp/buptest/*/latest
	      ...
	      umount /tmp/buptest

SEE ALSO

       fuse(7), fusermount(1), bup-ls(1), bup-ftp(1), bup-restore(1), bup-web(1)

BUP

       Part of the bup(1) suite.
