Good way to build a grid in Photoshop, Illustrator or InDesign?

If you want to warp similarly in Photoshop, you can turn your image into smart object, the choose Edit/Transform/Warp, and manipulate the mesh. Your image and the mesh warp will remain editable ad infinitum because you are working with a smart object.

I'm using CS4 and just noticed you can't warp a smart object.
I can, even in CS3, which is what I'm using here at work. Is the feature grayed out when you have a smart object layer selected?
Ok, I never realized there was a difference between a vector smart object and a smart object. I was trying it with a vector smart object.
