As mentioned earlier, despite very little information on the subject from D-Link, the G600 has the capability to act as a UPnP based multi-media server. What this means is that you can add content such as music, movies and pictures to the G600, and it will serve them up using the UPnP Audio/Video (AV) protocol. There are a number of devices on the market that support this protocol. For my testing, I used a device that I already have on my network: the Buffalo LinkTheater [reviewed here].
The basic idea is that the G600 will scan its drive to catalog the media available, then send the results to a client device for display and user selection. Upon demand, the G600 will stream the media to a client device such as the LinkTheater for display or playback. Figure 10 shows the main menu of the LinkTheater once it has connected to the G600.

I found that the G600 worked fairly well in this mode; I was able to play LinkTheater-supported music and video from the G600 without issue, though there were a few oddities. For example, all of the album art from my music was shown in the photos section. I guess some people might consider this desirable, but viewing a slide show of album-art isn't on my list of things to do. Also present was a "Playlist" folder, but there was no documentation on how to create a playlist. Finally, a "Genre" menu was presented, but all of my music was categorized as "Blues".
