Surveys in Marketo using Cvent?

Hi, 

I talked with Cvent at the DC area Marketo Roadshow, and the lady I spoke with told me that Cvent does surveys and integrates with Marketo.

I know from digging around on this topic a few months ago that the inability to create surveys in Marketo are a big pain point for everyone. Has anyone tried Cvent? Maybe this is a new functionality, and I haven't explored it with them in depth yet...just wondering if it's worth my time to dig into or if it's known in this community to be an unworkable solution.

Thanks!
