I'm quite excited by the Google calendar/iCal integration.  I had 
previously written a simple Ruby script (I really need to learn elisp) 
to parse an org-mode file for dates and schedule some "at" jobs to fire 
another script to fire events into Twitter, which I was subsequently 
using as a free SMS reminder service.

It worked quite well in simple tests, but I've never bothered to develop 
it further, primarily because it occured to me that google calendar 
supports free SMSing of notifications and that this could potentially be 
tied into org-mode with the g-client code.

It seems that your code is about getting gcal into org-mode where as the 
above would require the reverse.  Obviously the ideal would be to have 
some level of two-way Calendar synchronisation.  Though this might be 
far too complex and messy, how about allowing some kind of emacs based 
copy/paste between them (in both directions)?

The thought of managing myself in org-mode and syncing to Gcal when I 
want to share/expose my calendar to others is a tempting proposition; I 
imagine this coupled with SMS reminders would be great.

Anyway, as my elisp skills are no more advanced than being able to copy 
and paste fragments of elisp; I thought I'd post my ideas to see whether 
anyone else finds them interesting enough to implement.
