Conference schedule enhancements

I would suggest to enhance conference schedule by:

1. add option to download iCal (or common calendar format) calendar files which can be stored in attendees mobile devices
2. add option for registered users to personalise schedule and select tracks into your personal list... to ease up planning of attendance.

This would actually help organisers to see potential interest on topics (how crowded rooms might be) and attendees would see if they have selected all tracks they are interested.
In addition there is no reason to have schedule on paper - save money on printing and save nature by not generating additional waste.
