The short answer to your question is NO. Right now the cave-mode and the
tiled-diplay-mode are sort of mutually-exclusive. At any time you can use
either one but not both. The cave-mode currently only uses the
data-server::client setup but not the data-server::render-server::client
setup. We will keep this requirement in mind for future enhancements to the
cave-mode. Like Aashish mentioned, our current round of funding focuses on
interaction, enhanced stereo and the bringing in ability to plug-in numerous
input (primarily tracked input) into the cave-mode.

I will let someone else answer this question. But I would like to
