AirDrop over Ethernet

I don't really use wireless on my mac mini or iMac and so I was bummed when I found out that AirDrop doesn't work over ethernet.  

Luckily I stumbled upon an article on Lifehacker

here:  http://lifehacker.com/5939804/enable-airdrop-over-ethernet-even-on-unsupported-macs-and-hackintoshes

To the point,  run the following in a Terminal session:

 defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1 

Then restart Finder with 'killAll Finder'
 
Note that I needed to enable AirDrop in the sidebar under Finder preferences.
