Tweetrush for enterprise?

Much has already been said about Tweetrush, the service that allows you to get statistics on your personal Twitter usage. I particularly liked Bernie Goldbach's commentary where, among other things, he says:

Tweetrush is Sweet Infoporn. I like stats. I like comparing like to like. And that means I like the infoporn hit that I get when clicking through Tweetstats. Tweetrush is powered by a real analytics engine using PHP and the Zend Framework. It's displaying only the tip of an iceberg of live data.

That got me thinking. Using Tweetrush, I can look at pretty much anyone's Twitter usage (except those who are so unsocial as to protect their Tweets to a select audience.)  If that's the case then as an enterprisey person, I've got an instant monitoring tool. Now that's what I call a good idea although I'm not so sure the free thinkers in the Twitterverse would agree. It also reminded me that when looking at my own Twitter usage, the rumor that I don't sleep could well be true. (see image above.)
