We have a (gentoo) linux CAVE here in Sydney (UTS Data Arena) and are definitely interested in this too. Especially working with the Houdini Engine. Presently we run Equalizer & Omegalib & OSG to perform parallel graphics. Hmm was it written somewhere in the rel notes there is a “working linux version”. Yes, the docs (URL above) seem to only mention Windows. From a brief look at the header files it appears that you need to start the server and clients yourself, and then they talk to each other and keep sync over a port.

Also, it seems a mistake to put VRPN is under the “nDisplay/ThirdParty” directory - I would have expected it to be independent, in it’s own directory. It’s not really related to multiple displays as such. It’s about I/O - Will it be moved later?
Also, pleased to see “topBottom” format, which is the stereoscopic format we prefer (though we’re active stereo). hope this would work as imagined.
Will be watching for updates.
PS. “umm” is a local linux alias to find(1) files recursively
