On the technology side, I'm somewhat hopeful because it looks like they're using off-the-shelf HP ink cartridges for this. HP cartridges embed the printhead into the cartridge itself, and that printhead is arguably the most complicated part of the entire device. Outsource the printhead, and you're just designing a plotter with a PCL interface.
I agree that the bigger challenge is going to be patents.
It also wouldn't surprise me to see HP add DRM to cartridges to authenticate the printer itself if this catches on. (Possibly requiring a printer driver/firmware update.)
