Greetings!
You can give up on the source becoming public. That issue has already been discussed a few times. Given that the developers / designers / creators of the empeg are still here and active, and are still using the same code base, I suspect that there will be more code along the way. Granted, maybe not in the immediate future, but...
If it is not breaking a confidentiality agreement, could you let us know what release number the current alpha team is using? I know the alpha team is a number of releases ahead, but if you choose to publish any information on the alphas past (what number and when it was released), it might help ease concerns. If the answer is "no", that's fine too...
