is it possible Serverside

[fastboy619]

so I plan to have one Caster and many listeners is it possible to stop a listener from also casting(if he hacks and gets into the code ofcourse) on serverside?

On the SFS/RedBox side this is not possible to prevent a client from sending his own A/V stream.
Maybe you can achieve this on the Red5 side, by means of custom server-side code, but we are not expert in Red5, so we can't help more than this.
