If you have a reasonably connected server with a static IP address (see the requirements), please join the pool. Literally millions of users are counting on you! Any old server that can keep track of the time can run ntpd too. The cpu requirements are really minimal, so your current MySQL/Apache/whatever load is not going to be affected. If you are able to setup a GPS antenna then you can also go apply for the GPS devices. They are really really cool.
Or in any case, if you are able then please give us a link from your weblog, a "digg" on digg.com or a link on del.icio.us.
