OSX: Enable Lion's Airdrop on unsupported Wifi cards / USB dongles

gistfile1.sh

# Lion includes a new technology called "AirDrop" which is Apple's name for adhoc wifi data exchange.
# 
# When two machines that both run Lion are visible to each other (nearby , "ad hoc networked"), 
# users can launch Finder, go to "Airdrop" in the sidebar and will see each others Machine. 
# You then can simply drag and drop all sort of documents onto the icon of the mac next yours 
# without having to think about setting up a network or dig deeply into Networking details.
# 
# This new technology is not enabled for all wifi "Airport" cards and never for 3rd party devices
# (usb dongles , pci cards etc that have OS X drivers available)
# 
# Now here is how to enable Airdrop on EVERY wifi device, regardless of vendor make or type. 
# The device needs only to work in Lion of course.

defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1

# Then Restart Finder or restart your computer

# However you have to do it on the other Apple machines to let them see your machine with a non-Apple wifi card. If not, this machine stay invisible for the others 


# Keep in mind that this doesn't enable the feature on your Airport card. 
# It just allows Airdrop to run over whatever other network connection your have. 
# Who knows what havoc it might cause on a workplace LAN with lots of users doing the same. 
# I would imagine there is a reason that was not enabled by default. 
# I can't test that, so I couldn't tell for sure what it would do.
