'Medium Grained' API Access? + xCal

Three quick questions;

First;

I understand fine grained access to the API is on the ToDo list - In the meantime is there any plans for a temporary solution e.g.

"The following application is requesting READ ONLY access to your account."

"The following application is requesting READ AND WRITE access to your account."

For my current project I only wish to verify the user, full access is way beyond what I need and what people will be comfortable to allow.

 

Second;

Is there a reason why the dtend xCal tag in the XML feed is not used when the duration of the event is within a single day? The examples in the following IETF use it;

http://tools.ietf.org/html/draft-royer-calsch-xcal-03 (Examples 3.4 / 3.5)

http://upcoming.org/syndicate/v2/my_events/89346 (My feed)

Third, and last question;

Google Calendar parses times (and therefore dates) on the iCal feed incorrectly. Is it this feed or their parser?

I'll be sure to post my small project here when complete..

Many thanks in advance,

Kind Regards,
