I do a lot of RTT in my app with the need to pipe the resultant texture

difficult it would be to implement the use of PBOs in OSG to facilitate
fast texture readbacks. Any suggestions?
I haven't tried PBO's for readback before, for uploaded textures I found I got a 10x performance improvement so its certainly something worth pursuing. I can't comment on how easy using it for readback is, or how to go about integrating it though, you are out in unchated terroritory :-)
