Never mind a bot farm, this is incredibly useful to anyone who has just one 3d printer.

Normally I have to sit with my laptop plugged into my printer by USB for the full duration of a print, which can be hours long. This lets you print from wherever you want in the house, and cuts out the crappy slicing and print hosting software you currently have to use.

If you can really print in 3 clicks like they say they can, I'll be sold.
