Maybe just put it in a dropbox link.
I think that is just the same as midiOut.dll

Mike Lucich posted that in 2011 and even with 5000 + hits it has still not been implemented, so I think wishing ain't gonna help.

The VSTHost is the easiest option as you can set it to start with Windows and sit there minimized, then you don't need to do anything. Coyote is not that good a synth, there are better soudfonts that will load into VSTSythFont or if you have the Coyote Forte you can convert it to a GM sf2 and load it into SynthFont.

Also another easy way, if you want you can use http://www.hermannseib.com/english/savihost.htm
copy savihost.exe to your plugin folder and rename it to the same name as the vst eg: VSTSynthFont64.dll so rename savihost.exe > VSTSynthFont64.exe and set the midi in - out (see pic below), now create a shortcut for VSTSynthFont64.exe and place it in the Windows Start menu > Startup

The next way is just use an action script like AutoHotKeys,
one hot key will save the song as a midi file, Import the same midi's chord track channel, then all you need to do is load a preset on the chord track that loads midiOut.dll, once you save the song it will keep the chord track and midiOut.

Or, wait another 7 years and maybe you will see a midi out in the Output Chords dialog ????
