I have a question regarding if anyone is working on dynamic shaders for the blender internal renderer? It would be nice to get new shaders to blender without recompilation of the renderer.
without recompilation of the renderer?
hrmm, you can load texture plugins, which can do some interesting things. Eeshlo (iirc) had a refraction plugin which when set up properly mimicked refraction (but meant you had to do lighting on a seperate object... or similar)
as far as vertex and pixel shaders like in the newer opengl and directx api's it isn't possible. Cessen said (on elysiun, like today) he was working on something similar (don't know exactly what atm) but his work has stopped and it seem nobody else is working on that.
