it's not a commercial project - they released all the info for people to make their own hardware floppy disk emulators. The original surface mounted FPGA was a bit daunting for the average electronics hobbyist, the MCU version though should be a lot easier for the average electronic jockey to make. I'm sure you'll see pre-made units for sale on ebay eventually.
once the schematic and MCU code is released, then there's no stopping you doing a little re-design and losing the LCD etc. if you want (the LCD I'm guessing allows you to see which ADF etc. images you have on your SD card and select the one you want for loading. Similar with the three buttons (eject / load / next maybe?)).
