It's still very early in development, so isn't available to the public yet - we're hoping to release by the end of the year, but can't promise anything. I'm with Raspberry Pi, and got it directly from Mojang. I don't plan on featuring anyone.
I had no need to contribute anything here before now. Would you prefer that I didn't answer the questions? (Three posts now, by the way.)
Well, I have until the end of the year to get 25 dollars (that means 2 weeks of work for me here in Argentina...but it will be hard with the dollars). I want the 512 mb ram version so I can play well. I'll see how much does it cost
