Hi Charles,
Right now I am afraid that isn’t quite possible. We do ship a CSV importer as part of The Events Calendar and addons like Facebook Events bring the capability to pull in events from a Facebook account – but it cannot by itself be set to automatically pull in some other type of feed.
That said, it would certainly be possible as a customization – just not something it can do “out of the box”.
I hope that answers your question, but please let me know if you need any more information.
