Vertex based animations in Unity

Hi,

In your forum I read on an old post (2009) that Unity3D will support vertex animations soon, so hopefully 2 years later this feature is now implemented.

So my qustion is :

How could I import vertex based animations from maya and use it in Unity?

If Unity still does not support vertex based animations - is there any third party solution out there - even if its not cheap?

thank you in advance.
