It would be very sad if this project would be abandoned. I just found out about this and after fiddling around on it for 2 days I have anything up and running like I need it to. I would also like to contribute to the project if possible. So before this project gets abandoned please consider about making it open source. If there is anything else I could help with this project, please let me know an contact me! 

This is more a workaround than direct help, but how about attaching a USB storage? I had a RPI Server running and found out the SD-Card was a huge bottleneck and switched to a SSD attached via USB and it was a huge performance boost. Its also possible to boot from USB.
