Re: [PHPiCalendar-DEV] Shared Editing of Calendars

[Dietrich A. <aut...@gm...>]

edit-ability of remote calendars is determined by the server. webdav 
*should* work out locking, etc. however, both mozilla calendar (sunbird, 
tbird extension) publish the *whole* calendar. in most cases, publishing 
*replaces* the existing file on the server (if you have some custom 
storage solution behind the webdav server, this may not be the case). so 
it's not really simultaneous editing of the same calendar by multiple users.

also, some "webdav servers", such as the publish.php script in 
phpicalendar, are not really dav. the publish.php script just dumbly 
writes the calendar to disk. no locking, no versioning.

lightning, the in-development calendaring extension for mozilla 
thunderbird, supports caldav. caldav is an extension of webdav which 
allows granular editing of calendar components by multiple users. this 
should ease group calendaring once available. however, it will require a 
server that supports caldav, and there are basically none at this point 
(hula supposedly has support, but last i read on the developer's blog 
it's not really been tested at all).
