getclicky.com monitors over 200,000 sites and it's real time. Sure it's challenging to provide that level of service but without challenge life is dull.
I only meant to imply that providing such a feature is more work than a "few lines of code" when you're trying to monitor millions of sites in real time.
Oh, ok. I interpreted your comment to mean that no major service could pull real time analytics beacuse it's just too hard. Sure we're a lot smaller than Google but 200,000 is a pretty big number if I do say so myself.
