1: If you're going that route, you really want chroot cages. Look over at
sourceforge.net for available chroot tools for SSH. I used to publish
patches to do that, but got busy with other projects and the OpenSSH authors
have consistently rejected the patches for various policy reasons. But it's
consistently turned out to be the right thing to do, since restricting user
access once they've SSH'ed in has otherwise turned out to be quite
difficult. I highly recommend Richard Silverman's book on SSH, and hopping
over to the SSH newsgroups for more details.

2: If you don't need to actually give them shells, and just want them to
securely exchange files without shell access, look into WebDAV running under
Apache using HTTPS. I've used it extremely effecively for exactly that sort
of access, and graphical drag&drop is built into Windows, the Konqueror web
browser, and published Java widgets for other OS's.
