but what about jerbs?
Opensecrets.org says John Deere has spent more than $1M/yr on lobbying in some recent years, but it probably wasn't to combat printable lawnmowers.well you could download one, but then they'll just modify the DMCA to prevent lawnmower piracy too.
i can see it now, "SOME ASSHOLE PUNK STOLE MY ROBOTIC LAWNMOWER FROM MY FRONT YARD!"
Sadly with how ridiculous the copyright system is now days I could easily see it get in the way of 3D printing and making it illegal to actually print certain things, like parts.
I wouldn't download a lawn mower with UDP since the packets might get out of order and it could be dangerous! TCP should generally be safe enough to get the packets correctly.
