i thought that alias_smedia module did already this!
<snipper from code>
Alias_smedia.c is meant to contain the aliasing code for streaming media
protocols. It performs special processing for RSTP sessions under TCP.
Specifically, when a SETUP request is sent by a client, or a 200 reply
is sent by a server, it is intercepted and modified. The address is
changed to the gateway machine and an aliasing port is used.
