RSS to Calendar plugin needed

I’m working on a website which needs to have a calendar widget that populates from an external RSS. This RSS feed lists all of their events and links to the registration. Anyone have any ideas?

Why not just import calendar items as entries, map meta data to custom fields, and use entry date/expiry date for the event start/end date?

The goal is to link from the widget directly to the event service. It’s there a way to do this?
