Just wanted to report that have successfully streamed Video , Music, and Photos from the shared folders on WHS. I had a few issues between WHS and Vista so I recommend using XP (for the NDAS driver) at this time. All video played back without hesitation, pauses or skips. There seems to be no problems or negative interactions with the NDAS networking protocols and WHS.
Anyone looking for a great way to stream video from WHS (including HD) should check it out. http://www.divxtech.com/rapsody_n35.html.
