I am currently building a protocol in which each stream can be any combination of (un)reliable,(un)ordered,datagram or datastream. Yes, some combinations make little sense, but it can be done. You only need the control stream to be reliable+ordered. UDP datagram limits you to the size of the packet. The basic difference of datagram and datastream is only wether you have a way to identify the start/end of the user messages. Think like TCP, were you don't need to handle the beginning and end of your messages.
