Checkout the security/openssh-portable port which has options to enable
chroot'ing. You should be able to configure the account to only be able
to use scp(1) or sftp(1) by editing sshd_config or by using forced
commands in the user authorized_keys files.

Another alternative is WebDAV. Run it over HTTPS for security, and use
the standard Apache authn/authz controls to give each user access to
only their own area. In principle your users can mount their WebDAV
areas as networked filesystems on their desktops. In practice, this
works fine with MacOS X, is horribly buggy under Windows, needs quite a
lot of effort to make work on Linux, and I don't think it's actually
available at all on FreeBSD. However, commandline clients like cadaver
will work fine on anything Unixy.
Cheers
Matthew
