Yes. Sounds right. Could you try to check this?

This could be handled in drawSendAndRecv. Each workpackage contains the
viewport number. With this it is possible to assing the right buffer.
while(wI != _cluster.workpackages.end())
{
// !!! get viewport wI->viewportId
// check for stereo buffer
// activate correct buffer
channel = groupConn->selectChannel();
do
{
groupConn->get(&tile,sizeof(Tile::Header));
if(tile.header.last)

this would be solved by activating the right buffer before recv.

Currently I'm not able to do any development in OpenSG, but I think you
should be able to fix this problem. I'll try to help you by mail.
