You could just pop Varnish cache in front of Wordpress to do the same thing - any unauthenticated GET's will just hit Varnish, and come nowhere near Wordpress itself.

That way you wouldn't need to worry about software updates.

Totally. I guess I could also use some advanced Nginx directive/plugin to do that. The hack is just something that occurred to me spontaneously, it took about 2 minutes to implement, and I didn't even have to install anything :)

You could give these 2 config files a try sometime:

Basically they make nginx cache itself, which combined with this Wordpress plugin:

Makes things very minimal, no need for even a dedicated cache :)
