It would be terribly easy for you to spawn a process that has a 
reference to the TCP socket, registers itself and turn signals you send 
it into gen_tcp:send().

In the SIP server I'm working on (Yxa), we do something like this and
also lets the registered process have a list of all TCP connections 
that are active so that we can use existing sessions instead of opening 
up new ones for every transaction. If you are interested, look a the 
sipsocket* modules of the Yxa source.
