Ok, so I tried this:
mpdboot -v -n 2 -f mpd.hosts --ncpus=2
running mpdallexit on xenia.gl.ciw.edu
LAUNCHED mpd on xenia.gl.ciw.edu  via
mpdboot_xenia.gl.ciw.edu (handle_mpd_output 406): failed to handshake 
with mpd on xenia.gl.ciw.edu; recvd output={}

I don't know whether there is a linebreak after "via" in the 2nd line 
(i.e. if it actually reads "via mpdboot") or if something is actually 
missing, but that's all I get.

This version *should* work - I have used it before the shutdown this 
way, and no updates have been made since.
