Yeah! It's really nice to be able to transform the warp like that in Nuke.
Another real-world example of how Mesh Warp in it's current iteration didn't quite stand up: We were testing the idea of creating projections on people's faces as a post process for this Adobe spot we recently finished. (link:

Ultimately, we just shot the projections in-camera for a lot of reasons so it became a moot point, but I could have stayed in AE with a better Mesh Warp.
Not trying to beat a dead horse ... and I did submit a feature request. :)
