yes i could...or better yes i can :-)

I know, probably vvvv is the better choice to do this - but first i want to try it with GEM. i started with two screens, two pd instances, two gemwins framesynced over netsend/receive on one machine. for edgeblending i use pix_takealpha and a matching tif with alpha channel.
