I recently purchased an Acer Aspire One Netbook.  I am running the Ubuntu 8.10 beta on it and have most things working (sound from the speakers is very low.. but it works).  I also have MediaTomb server running on my main computer that serves songs to my mp101 scattered around the house.  Instead of mounting a share and importing the songs into Rhythmbox or Amarok I would just like to connect my netbook (when I am at home) to my uPnP server (I dont have to keep mediatomb).  So far I have not found much information on what programs can do this.
