Calendar Feed?

[Robofuzz]

I have searched and searched but have come up empty with anything helpful.

Basically, I am just needing an RSS feed of the current day's events. Like external.php provides for the latest posts. I just need something simple like the Upcoming Events widget in vBA with just an event title and a link. Anybody have anything? I can't believe there's not an addon for this as it seems like something many people would want.

I am not opposed to rolling my own, but I'd rather not reinvent the wheel if this is already available somewhere. If not, does anyone have any documentation on how the calendar tables relate to each other, how dates are stored, and how repeating events are handled?
