How would streaming Netflix work?

[Saruk]

I know Netflix is coming out for the wii and will allow the Wii to stream Netflix.

But I never used Netflix before and I am interested in getting a subscription to use on my Wii. I'd just like to know if anyone here has streamed Netflix before, Possibly on your PC, PS3, or Xbox360, knows it works.

Like I see that you can order one movie at a time to be shipped to your house on DVD or Blueray, in the basic package. But what I want to know is if you stream Netflix like on your Wii for example, are you limited to just watching 1 movie at a time? Like your just ordering them. If anyone knows how it works I would really appreciate if you could let me know, thanks.
