Does it make sense to use class.gzip_encode.php as a fallback if it is for 
some reason not enabaled in PHP?

And another idea: how about storing the gzipped content in the cache? We 
still can deflate the cache content if the client doesn't accept gzip 
encoding. But I guess that most clients do it and decoding costs less 
performance than encoding.
