Wonderland is right. It would be wise not to expect them to open it up to the public. Remember it's a beta trial. I think they might have a batch size of 5 to 6 or at most 10 as a smaller sample size would provide them with effective monitoring of the progress of the program. Then again, I might be wrong.
You could use this analogy. If you want to test a new drink you were just introduced to in the market, you will take a small amount of it in your glass and sample it to decide if you like it or not before you take a glass full of it.
