Yeah - I didn't think there would be confusion with the networking tool but based on feedback we're receiving...I was wrong. We're considering options including changing the name.
You're in a niche(ish) space, that doesn't have a lot of general overlap with HN.
I can say "I wish someone made a cheaper alternative to the Domino" and anyone in the space will understand what you mean instantly. But from an original analysis others might of told Festool that it was a bad name that will confuse people.
The HN feedback is likely heavily biased… even if you are deploying your product in Silicon Valley. Most people that will be fishing wire through their home have never heard of the networking tool. ie: You might consider not changing it too :)
