Scaling a vision?

Guys I was searching for some interesting pod casts on scalability... More like scaling hardware, databases. storage and more shit like that.. But look what I got myself into.. Scaling a vision.. Listen to it.. It has very much influenced my thinking lately..

tweet a what??

you can tweet-a-watt.. Can someone tweet the calories i am burning? What else can we tweet?

Boxee Hardware..

I have zeroed in on boxee software for building HTPC (I rather call it a STB). I like boxee from what I have seen, heard, imagined and understood so far. But for some one who is unbiased here is a survey or rather choices that might be of help (or cause a headache).

I read an interesting article about Boxeebox. There were some more interesting thoughts like having storage separate from Boxee device so that it is quiet (it is like saying run boxee as a media extender).

I have installed boxee on a old Sony vaio notebook. the boxee was very slow on it. it needed a more powerful pc for sure. I need a new machine.. it got me thinking..

I have few options
1. install Boxee on 1080p supported AppleTV (around $300)
2. Get a powerful pc with Ubuntu installed ( can boxee take advantage of multicore.. what i mean is video decoders...as far as I know libavcodec that boxee is based on does not have multicore support. ). What Graphics card to use?? NVIDIA is most compatible on linux boxes. If I get a powerful NVIDIA graphics card.. I am not sure if boxee playout can take advantage of such a powerful graphics card.

I am more confused :( help me out somebody!!!
