I could have new custom hardware working in a few weeks without much effort. The software side however always seems to take much much longer.
You can use an off the shelf Allwinner board right now (~$50) with an Ethernet or PCIe Mesa FPGA card. Getting the open mali drivers working on the Allwinner will take a couple weeks. Have to take a look at what to do with getting Visual Basic Macros to work with LCNC.
