Did you ever get anywhere with this? I just did this yesterday.

My solution was to just render to a framebuffer, then use glReadPixels to read it into memory for the CPU to then process and send over the network (via ArtNet, to some DMX controlled LED strips)

I tried to use glGetTexImage to read the pixels straight out of the texture, but that didn’t work.

I can share my code if you’re interested.
