Elevated Events RSVPs Online

My Development team has asked about the ability to have an RSVP form on TNEW, that records those RSVPs in Elevated Events, without the need to purchase anything.

Does anyone know of a way to do this, or any product that integrates that would do it? My understanding is that WordFly Pages (and possibly Prospect2?) would allow us to email the RSVP form, but it wouldn't support a stand alone website, but I may be wrong there - we are just starting to implement Prospect2.

I could hypothetically set up a free ticketed event for RSVPs with a custom form and procedure that populates the data, but I feel like that would be clunky and potentially confusing for our donors, especially for events at this level, like a Gala.
