(Granted, I'm not sure RTMFP is the best argument for your point anyway,
since apparently symmetric NAT monkey-wrenches it, too:

We have agreed to disagree on the value of this before.  Sorry your not so
popular protocol is going the way of EGP .... it's just not fit for the

because rtmfp is top of mind for so many users .... but we can leave it at
