Ive used OSG on RedHawk. In fact, many trips around the sun ago, I used to be a systems engineer for Concurrent Computer. IITSEC of 2003 I put my hang-glider simulator in Concurrent's booth and drove a cluster, using the ccur running RedHawk as the master channel. The role of graphics does not really call for hard-real time, but some of the other activities associated with the simulator did, including the frame scheduler and synchronization of the slave channels with the master.
The real-time extensions that CCUR brings to the Linux kernel are the same ones they've been using since SVR5mp in the early nineties, and conform to Posix 1003.b and 1003.c real-time standards. The extensions allow for a fully preemptable kernel with resource allocation and very good thread priority support.
My experience was quite positive with Red Hawk.

I am working on a project which has as its end goal a hard real-time
system using OSG for the rendering. I have been considering RTLinux
Pro and RedHawk Linux as my RTOS. Anyone have any experience, good or
bad, with OSG on RTLinux or RedHawk? Anyone out that using OSG in
hard real-time?
