More generally, I think you can use a restricted shell that accepts
commands to run via the -c argument, like standard shells, but
will only run a few selected commands, like say, sftp-server and ls

The sendmail restricted shell "smrsh" might be adapted for this
porpose, or you could write a perl script (be careful about shell
metacharacters, and pass lists to system or exec, not strings.)
