Right. I don't think there exists any "dummy data stream" type of
input/output in mosh, only the terminal handling which isn't very useful
for scripting purposes.

mosh <host> <command> does work for me, but it also assumes that the
output goes to a terminal. For example:

# mosh host 'echo foo'|wc  
      3      10     684

vs.

# ssh host 'echo foo'|wc 
      1       1       4

It doesn't mix them (just verified).
