@Lars: If you would have asked me this 2-3 years back (when we really started to rethink the scheduler) I would have said: we will go with the RadScheduler of Telerik. But things have changed, like you mention. It has served it's purpose, but not any more.

We are investigating open source jQuery based schedule/calendar controls. If you have any suggestions (or experience you ard willing to share), they/you are most welcome.

@John:

The DNNEvents module will/can only use fully open source calendar controls, we really need a back-end (the current code for managing events is very extensive), it should have a responsive design with templating options.

The DNNEvents team has nothing to do with the Invenmanager (which was a very nice commercial events module, but the supplier has vasnished, without leaving the source around). So people using this module are now stuck.

In my company we are stuck with one implementation as well. So join the club :-(

I think there is an initiative going on to collect source code (there was an option to buy source code for version 5 or lower). The latest version (6): there was no source code option. I think the group will try to decompile the latest version and recreate the source. A bit illegal mb, but that would be an solution.

WRT Time frame: I have a new version in the works, but still have to solve an issue with teh scheduler control in combination with DNN732 (DNN732 broke the calendar/schedular control). Haven't solved that yet, is a bit complex MS AJAX/JQuery/Telerik postback problem...
