Is there anyway to have some import and export functionality? 

It would be good to be able to import bulk events, i.e.

• from public bodies, organisations etc to the sitewide calendar and open to anyone.
  
• from Group owners for events to their Group Calendar open to members of the Group, or open to anyone.
  

It would be good to be able to export events that you are interested in from the listing by iCal file download.
