I'm not sure I agree with that.  You know where you go wrong because you
have standard out and standard error streams to read from your Net::SSH
object.

You would trouble shoot it the same way if you ran the script from the box.

When dealing with channels this isnt much different then loading the file
to the box, running it, and reading your return code/stdout info.  Except
you dont have to load the file to the box, which is what your trying to do
anyway.

Good luck.
