Steam streaming over local network (my laptop is a potato)

Has anyone attempted to use the Steam stream functionality to play the demo remotely using the Stream option?  I've only got one machine here that will run it, but was hoping to stream it my laptop so that I could play it in a more comfortable location than where my desktop is at.  Doing this seems to have fixed the molasses slowness of running it on that machine, but I'm unable to play because the controller I'm using is acting goofy.  For example, pressing the X button moves the cursor up on the menus.  I'm trying to decide if this is a bug, or I just missed something in the initial setup for this that I've missed as every other game has played fine on the laptop without needing to worry about streaming from a more powerful machine.  I was hoping someone else here has already come across something similar.
