To be honest OGL 3.0 is not on my horizon right now ( I know its there ) A lot of our customers are on base line machines with 7 year old cards such as NVIDIA Quadro4 700 XGL OpenGl 2.1 and 256mb is a luxury :)

Moving forward, the preferred method for dynamic data will be buffer objects with glMapBuffer or the new map sub-region functionality. The ARB defines "deprecated" as: * Not the optimal performing path -- use something else * Might not work properly with new functionality * (Obviously) could be removed in a future OpenGL release For all of these reasons, I'd prefer to see any new OSG development avoid the use of any deprecated OpenGL functionality. (*) Even after they are removed, you'll still be able to access the glBegin/glEnd and display lists features by restricting yourself to creating a 2.1-compatible context, or using extensions with a 3.1 (and beyond) context, but it's uncertain how long vendors will continue to provide this functionality. Presumably, not forever.
