Re: [manet-dlep-rg] Example: TCP server on satcom modem

OK. 

I talked with the Persistent Systems folks this week at MILCOM. Their response was that they don't care whether the radio (modem) is the TCP client or server. 

So, if they don't care, I'll change my position to "I don't care, either". Other than the fact that I think making the modem the server looks completely backwards to me. Let's wrap this point up and move on… what is the consensus of the DT as to what should be in the spec? 

One side note I feel compelled to point out - if the consensus is to make the modem the TCP server, and there's pushback in the WG on it, don't expect me to defend the position.  One other comment inline:

While multiple connections on a telnet server makes sense, I don't think multiple connections makes sense on DLEP.
