Dirk, Allen,

Nice to see you picked up the news. :)

I just stumbled upon this thread on the web. I am the main
developer on Equalizer, please allow me to add my 2 cents.

Imo it is mostly orthogonal to OpenSG. Equalizer has a generic
parallel rendering API, which might be used by OpenSG, among
other applications. An integration of OpenSG and Equalizer has a
number of advantages in:

- Integration: When running several Equalizer applications
   concurrently, where some use OpenSG, the server will be
   able to do resource management between them.
- Configuration: Single point of configuration for users
- Features: some of the functionalities implemented for
   other applications will be beneficial for OpenSG-based
   applications.

Honestly I haven't looked into what features OpenSG already
provides, and which are also in Equalizer. From previous
experience there is however a lot to be gained from having
a scene graph for scalable rendering, esp. when it comes
to load balancing and efficient data distribution.

A distributed scene graph based on Equalizer is on my radar, but
the priority is currently not high enough that I will realistically
get around to do this in the near future. That said, I am happy
to help out where needed. Ideally somebody familiar with OpenSG
could take on this job, and I can give advice when it comes to
Equalizer. Dirk - do you know somebody?


Cheers,

Stefan.
