Dig Deep Into Lion: 17 of the Best Overlooked and Underrated Features | PCWorld – StumbleUpon. I didn’t know many of these items. It is helpful to read if you want to get the most out of Lion.
You can’t use AirDrop over ethernet, so if you try to connect to a wired machine, it won’t work. Kellow goes into more detail below.
I might have found the reason behind the aforementioned behavior:
The AirDrop feature is apparently a Lion/AirPort-feature, and not a Lion/network-feature, meaning, if the iMac is connected to the network through a cable (RJ45), the above described behavior is the result.
The third issue mentioned, is apparently just how AirDrop works. AirDrop needs to be “activated” by Finder, which opens a ad hoc network though the AirPort. This does limit the use cases a lot.
Now, if only Apple would consider implementing AirDrop in iOS, the use cases would make a lot more sense…
This is an fascinating trick. I wonder how long Apple will allow this to work? This allows you to use AirDrop over any network connection including Wi-Fi.
