If your users are accessing the same websites, especially over dialup, the first user to access the content (provided it hasn't changed on the server) will be the only one to notice a performance problem. Everyone else who goes to access that content will pull it from the cache of the proxy server at the speed of your network. Also, a proxy server keeps lots of unneeded traffic off the Internet. Same might be said for caching DNS servers as well.
The web caching proxy server technology that seems very popular for Linux and Open Source (and which is used in SmoothWall) is 'squid'. You can set this up on pretty much any Linux system you have in place and point your browsers (even IE can work with it) to use your new web caching proxy server. Of course, you will need to configure it if you install it yourself; otherwise, SmoothWall takes care of that for you. IPCop is similar to SmoothWall. You might check it out as well.
