Snap: iPhone app that will scan your wireless network for hosts

Ever wondered if someone has cracked your WEP key and is using your wireless network? Ever wondered if who else is using the free wireless at the local coffee shop? Snap is an iPhone app that will scan a wireless network and tell you who else is using the wireless access point, which can be very useful for network administrators. 

Below are some screenshots of my home wireless network.
