Hi there, we have successfully built a Cave (4 renderind planes. 12 projectors. 6 graphical nodes x 2 nvidia 8800 ) environment using OSG 2.1.1 for rendering and mpi for synchronization and data distribution. it is feasible.
osg is well suited for some aspects. for example swap buffers synch for 2 displays in the same machine. But to build a rendering cluster you need multi-machine synchronization .. a "frame lock" so every machine "swaps buffers" at the same time. for this we used mpi's barrier and a extension of the osgViewer. but i think one can implement a simpler barrier using sockets. Another thing... glFinish is pretty important... on a rendering cluster.
