Previously I announced the first release a plugin providing a bandwidth limiting Throttle for WordPress.
In case you missed out, it provides an API for plugin and theme developers to selectively disable page elements when a site is unusually busy. This acts to reduce the effective load on the server keeping you within your bandwidth allowance and preventing your host from charging excess use fees.
Drupal offers this capability as standard and I would like this to become part of the WordPress core. If you agree vote for it here and we'll see what happens!
Suggestions, comments & everything else please!
