I'm experimenting (at the bottom of this page) with a referral system kindly offered by Stephen Downes. As Stephen points out, if you'd prefer not to send him your referral data, you can host his backend script yourself.
I haven't yet looked into what it will take to make the reporting item- rather than page-specific. It's doable, I'm sure. Thanks, Stephen! A JavaScript-oriented solution like this will appeal to a lot of Radio users.
