Will there ever be support for more then one RT feed?

After getting in a huge dispute with another player over the RT feed, I would like to know if there will ever be support for more then one? Because I’m getting sick of having to bitch and complain just to get the damn thing.

Unlikely.

Ask Valve; that’s Source’s fault.

Possibly with the next incarnation of Gmod. The orange box engine is capable of rendering multiple cameras, as demonstrated by Portals and dynamic mirrors, so it’s certainly not impossible.
