Lets say I've used a library like https://github.com/markuspoerschke/iCal to transform my event data into a ical feed.
This feed is then consumed by a client.
On the client they can see the events in their calendar.
When new events are created on the client, how can I get this information and process it on the web server?
Can this be done with something like ical? Where the client has a callback to the web server with the altered feed, containing the new events data?
Or is this functionality reserved only for apps using the native language to hook into native APIS?
