We employ a technology called libnative which is a bytecode manipulation and instrumentation library for Minecraft that we developed internally. We currently have libnative licensed out (for money) to other individuals as part of our completely proprietary NSEngine suite. Huskd is very tightly coupled with libnative. @brenhein is working very hard to decouple libnative from Husk, and until then we will not release either source of binaries because it contains proprietary libnative code. If we were to release anyway, we would be breaking the agreements we have with our licensees.
