We just started our first production series in small quantities. Due to still remaining issues with the Beast (prototypes work fine, but newer versions still have bugs), we decided to produce the face2|4 only at first. The face2|4 can be directly stacked on the BBB or BBG without any additional hardware. The drivers are already merged in the BeagleBoard.org kernel and are included in the default debian images for BeagleBone. Please send me a message with your name and desired units, if you are interested.
