AM Design has released Say What 1.0.
It enables documents, applications or AppleScripts to be launched remotely using a Web browser. Say What will launch anything that's placed inside its actions folder.
Features include the ability to define those IP addresses that can connect to the Mac, and to specify that only files in the actions folder can be launched. The app costs $40.
It uses the standard HTTP protocol, and can run on any port. The application is compatible with Mac OS X and older Mac OSs.
