The USB board are done and we have started testing with great results. The audio amp is done and we will be providing a power supply for the amp since in our testing the quality of pc supplies varies greatly and they arent a reliable source of power for the amp; plus is eliminates possible ground loop issues. Beta .98 was just finished and goes out for testing this week. I'm guessing there will only be a couple of additional *tweak* releases before go-live.
We're getting very close. The first packages will ship in July.
