Ian,

Thanks for posting about our just released beta. Some additional info…

We have limited highlighting: you can highlight by tag under the Find menu. you can tag and event blue and it will be in a blue font (we’ll add some more of those easter eggs). and you will soon be able to host and hack the css to create your own theme/scheme

You can access the calendar and One Box on any xhtml mobile client at
http://m.30boxes.com

We are working on our developer API and believe syncing will come from that community.

FINALLY,

30 Boxes refers to the interface. the One Box add (#1), 4 weeks of days (#2-29), and the pop up day view (#30)
