Thanks for your input.
Since CalendarBudget is calendar-based, I think iCal format is probably the best way to go for a read-only format.. but I also think more investigation on how this would really be used is needed.
Having CalendarBudget data show up in, say, Google Calendar, would look really awkward. But – maybe we’ll just have the daily balance available in the iCal feed, then when you click the balance for details, your daily entries are listed in the details… still not sure how we want to proceed on this front.
At any rate, I think a mobile app will take precedence and perhaps help resolve some of these issues.
