[PHPiCalendar-DEV] Outlook and iCal addition into phpicalendar

[svens <sv...@de...>]

I first installed phpicalender on april 19th 2006 after I had had a look at
it a year ago, or so. I too required a way for more people to add items.
 
I just made a little something with which some predefined users can manage
their personal calendar within my phpicalendar through email.
 
A dedicated pop3 (could be imap) account is used to receive the mail with
the *.ics attachments;
On each request (index, day, week, month, year) the mailserver is checked
for new additions and, if so, they'll be added into the calender associated
with the senders email address;
It's quite easy to set it up in a way that anyone can ad through this way
into a public calendar, but who would want that??
 
Anyway, when things can be added, they should also be delete-able, by the
adder that is. I altered the event.php in such way that the adder can delete
the item from its calendar, on uid-basis, from within the event popup;
 
Once the delete-option was made, it was also possible to add two other
options into the event popup: export item to outlook or to iCal, also on
uid-basis.
 
I did it in the last three evenings, so it's not fully finished/tested, but
also it was surprisingly simple. 
So now I just wonder why I can't find any similar addition to phpicalendar.
 
Why can mail_into_phpicalendar be preferable to just plain uploading of a
whole calendar or using webcal reference? 
Well, since anyone is used to his/her email application, one can expect them
to easily use it for emailing a calendar-item. 
Making it in your own system and then sending it, provides a backup, id's
and all the necessary data.
Using a form to add into phpicalender, would require a lot of choices,
possibilities, checks and balances.
 
I am wondering if anyone has tried the same and if i have overlooked any
(future) problem.
