Ralph Hempel released a new beta version of pbLua. You can download it via pbLua website:

What’s new in this version? It’s got some significant new features including:

1. The ability to turn the NXT off by pressing the orange button for at least three seconds

2. A startup screen that lets you select a Bluetooth device as the console. This will finally free you from the tether of the USB cord!

3. The RS485 high speed port now also supports standard baud rates from 1200 to 921600. This must be carefully used so that you don’t flood the 128 byte RX and TX buffers at lower baud rates
