The alternative has been around for a while, the chipset that came with the cartridge from Stratasys (SST 760 and 1200 ES) was cracked down by using a raspberri. It's safe play though, instead of breaking your 50k$ machine you break the cartridge that cast 200-400$.

I doubt that is hardly jailbreaking the system, instead it's the cartridge that has been faked.
