Are you sure this problem is related to the ":results silent" header
argument?  I would expect this problem to arise *any* time results are
requested from a remove R session.  This is because R and Emacs use the
file system to hand results back and forth, and when the R session
refers to a remote file system, this communication fails.

One possible solution would be to use the :dir header argument to
specify to the code block the machine on which the execution is taking
place.
