Security :: Restrict User To One Directory Only?

Here's the beginning of the issue: I'm running Fedora 12 with httpd and sshd. I want to create a user with a scponly shell for sftp access, but this user should ONLY be able to view /the/http/base/dir and its subdirectories. The user should not be able to see or get into directories above the httpd base. Someone mentioned creating a chroot jail for sshd and binding the httpd base to that dir, but this seems like more work than is necessary for the application I wish. Also mentioned was creating a user, say user1 with a selinux user setting of staff_r. I have read the articles and creating a user of staff_r isn't overly difficult, but how would I make it where staff_r would be restricted to where I want them to be? If I'm not mistaken, that would require changing the context of /the/httpd/base/dir?
