[Orgmode] Exporting of sexps to iCalendar

[Max]

Hi,

I am using MobileOrg to carry my Org-Mode files with me while being away
from Emacs. MobileOrg works excellent for my task management and note
taking needs. However, I often need to find a free slot in my calendar
or need to get an overview of upcoming deadlines and MobileOrg's agenda
views do not allow me to do this in a sufficiently quick manner.

I thus export my Org-Mode files to iCalendar and then import the
resulting file to my iPhone calendar via webdav. This works well
for most events with the exception of the limited support for sexps
in iCalendar export; I tend to use sexp quite extensively for all
kinds of recurring events or events that require esoteric date
calculations.

If sexps work in agenda views, wouldn't it be great to resolve them in
a similar manner when exporting to iCalendar instead of using the
rather limited icalendar-export-region from icalendar.el? E.g. could
sexps with multiple occurrences be resolved into multiple iCalendar
events for the next n days? I think birthdays that are captured in
BBDB would get properly exported as well.

Would this be possible? Ideas?

Thanks, max
