if you only want scp to work, then you can use this as the shell:

  /usr/lib/misc/sftp-server

worked for me.  however, if they need a shell, you'll have to chroot() the 
shell and i don't know how to do that.  i've never bothered to learn 'cause 
i've heard that they're easy to break out of anyway.
