since i'm running vgl and srss on the same server, i'm using rgb mode (basically a raw dump of the vgl X display data) and letting the sunray Xnewt handle it. i noticed that using proxy mode gives similar performance and jpeg results in additional input lag. because i'm running linux i don't have the sunray plugin for vgl, but i may try to alien the rpms and see if it works.
honestly, i think rgb is going to be the best mode to avoid having the image processed twice on the same server.
