Yes.

N/A :-)

I'm not sure what you mean.  The MCStreamer interface should have methods for all possible directives that can be sent to a .s file.  The problem here has nothing to do with text output, it is that we don't have a way to send the ".syntax unified" directive down a streamer.  The right fix is to add this support to MCStreamer.
