You can. This is one of the example of the French Erlang book 
(Unfortunately, for which I am still struggling with my editor to have 
translated in English).

Basically, you can use the handle_info callback to get message coming 
from a socket in active mode. You can use tcp/ip stream regulation by 
using the socket option active = once, so that after receiving new data 
on the socket, you need to turn activation on again.

I hope this helps,
