I'm not a caching expert by any stretch but I don't see how this would work. Squid would ask the web server if the content has changed, and unless you're publishing out static pages OG will always return that it's changed. Otherwise it's gotta do a database hit to see if it's changed anyway, and on the homepage that means the expensive recent changed database hit.
Like Simon I am interested to learn and discuss rather than an expert!
Do proxying caches remember the Modified: and Expired: header when they fetch a page. Or do they always go back to the main site and ask them for the headers for the page. And if they ask for the headers, might that end up as two hits?
