I've finally got around to hacking together a rotating channel display system for the ybox2. It uses a very lightly modified infowidget to hit a python cgi script on my server to hit an internet API and format and display the information for ybox (sorry - Spin is a little too daunting!) Each refresh fetches the next channel in sequence, on an endless loop. I've put a demo on youtube: http://www.youtube.com/watch?v=P4uMjhICRfU. Let me know if you've got any ideas, or if you'd like help setting up your own.
