Texture Paint additions in Blender 2.5?

First of all I’d like to thank ideasman42 for all the hardwork and all the devs who helped him on the image editor… I was wanting to ask, do you think with the current system that its possible doing 2d traditional animations using paint along with the dope sheet lets say, much like the open source pencil… if not, is it in the horizon ?

Ok guys, i am new at blender.
I managed to paint in texture paint mode. But how can i add more layers to my texture image like in photoshop? I cant find any option. And please be precise about that option. Is it on UV/image editor? 3D view? where? Repeat…i am noob here…
Thank you.
