I just posted this idea as a comment to Marc Canter's weblog. RSSCalendar should consider making the "ICAL" object an RSS 2 Enclosure so it can then be "picked off" automatically by tools interested in this data (without scraping the internal HTML object).

The ICAL object contains data that looks like this (original link):

BEGIN:VCALENDAR
CALSCALE:GREGORIAN

It's not XML but it does have its own RFC.
