This program lets you share business documents, contacts, presentations and other files with colleagues and friends via your AirPort wireless network on your local subnet. Drag and drop files and address book contacts into DataEnvoy, specify which Airport network you want your information shared in, and give your shared information a title. You can receive shared information from other DataEnvoy users. Just select Receive Shared information from the menu or dock icon and your DataEnvoy application will listen for any shared information in your vicinity.
