I'll look into that and maybe provide some additional fonts on a per OS/Browser basis to download. The main problem is that it's impossible to have a static CSS snippet AND provide different files per User-Agent (a javascript solution might help). So until I've found a solution to this, you are absolutely right, these optimizations will get lost on local use!
For reference: I'm currently using the following User-Agents for fetching the font file urls from Google's CSS: http://pastebin.com/5SZ1Q6kj
