I'm unsure as to whether you are trying to get your users <I>in</I> to your server at high-speed, or <i>out</I> of your server. I'll assume you are trying to allow users on your Unix machine out to the internet.

You could get a cable-modem, DSL, T1 or other high speed connection from your server to the Internet. Each user could then connect to the internet via ftp, telnet, www, etc. If you set up a proxy, they could do all this from anywhere on your local network. You will need to set-up a firewall unless you want to let bad guys in to your server from outside.

You will most likely need to read up on Firewalls, VPN's and Unix Networking to make this all work. If you are running Linux, start with the relevant HOWTO's (http://www.linuxdocs.org), otherwise you might want to invest in something like "The Networking CD Bookshelf" (link to book on Amazon.com below) from O'Reilly which will probably cover much of what you need to know (and much more!).
