I think the best thing would be a version of MC9 that runs on dedicated hardware like one of these boxes.
In the coming months there will be many more of these boxes coming out, lead by Linksys and all the expected companies. I am sure that these boxes can be set to run linux or an embedded XP.
So, JimH- is there anything you guys are working on?
I would buy 5 of these boxes immediately if they could run MC9, network back to my Media Server (also running MC9) and then stream all of my content wirelessly.
I believe that this is where all of this is headed. I love using my HTPC and MC9, but a dedicated box would be even better. That is why I am wishing for a better hairstyle. That would probably be the interface of choice for a TV.
I know that if I was building a dedicated box, I would put in 2 pci slots and a agp slot. That way you could always upgrade the audio card, video card, and networking card. All the box would do is run MC9, and would never crash or need boot-up time!
I am sure I will have my wish in a couple of years!
