OK this probably isn't over help full but I seen to think that CHROOT
may help lock users in.
Please feel free to let me know if I'm talking crap ;)

Why? They won't be able to access other user's directories nor do any
harm to a properly configured system.

For the simplest approach in form of http://foo.bar/~username, look at
Apache module called mod_userdir.

In commercial shared hosting environment, every user's database is
named username_dbname to prevent all kinds of namespace collisions,
so the DBs are separated, and only the user is given access to it.

I've used a commercial package for web-based shared server management
for Linux/FreeBSD called cPanel WHM http://www.cpanel.net/ It seems to
be overpriced, but I have no doubts in the existence of cheaper and/or
open-source management products.
