I have been using a lower end model on my commuter the past 10 13 years. And while the rear IGH has worn out at 30,000-40,000km (18,000-25,000 miles) the front is still going strong.
No maintenance whatsoever on the front and limited maintenance on the rear hub though.
The DH-3N80 is a higher end model with better quality bearings IIRC so I wouldn't worry about it too much.
