Edge blending

Is it possible to do soft edge blending with vvvv? I want to run five projectors together onto a curved screen with the video synced using boygrouping and I was wondering whether I could do soft edge blending with vvvv as well.

you could overlay a pillow: transparent in the center and fadecolor to black.

or use the multiscreen node…
