Can RTMFP (Multicast) do a Domain lock, swf verification?

Hi,

i want to know can we restrict Rtmfp to only domain names we want and SWF that comes only from my domain name ... to prevent iframe and embeding my streams in other websites.

This feature exists in RMTP but can't find it in RTMFP

if yes how can i do it?

if No is there another way to secure and prevent my streams to be embeded outside from my website?

if yes how can i do it please?

Thanks for helping me
