This is neat. What's the best way to do rate limiting in from of Apache for wordpress/drupal sites these days? everytime I go looking for something new I'm dissapointed.

You could use the OP's project and point everything that makes it through the limiter at Apache with a reverse proxy http://golang.org/pkg/net/http/httputil/#ReverseProxy

Use mod_security as most Apache installs already have it enabled and it achieves the same thing.
