No. Ever tried that on the linux USB gadget implementation in Linux? If a FD 
is not pointing to a socket, it can still point to a device file of whatever 
kind. You SO_TYPE won't completely help here. You can try any amount of 
guessing but isn't it easier if the application just tells you? OTOH, the 
application could just use a custom transport, then.
