You're not going to get that kind of detail from Netflow.  It doesn't 
have the visibility into application layer to tell you GTalk from 
straight HTTP, from any other traffic that might be riding on destination 
socket tcp/80.  You need something with visibility and intelligence 
higher up in the stack (sniffer, packet inspection engine, etc).
