It will be better to move VBO creation and binding on vertexbuffer.c. (its why 
GetMemory didn't provide VBO id before, no need for that)
Have you planned to use ti for index buffers too ?

For that problem i had a prototype who remembered too many lock (in small 
times) and active the no-VBO flag :)
