Does WebCom support Real Audio?

Yes.

WebCom does not run the Real Audio server, however Real Audio versions 3.0 and higher do not require the Real Audio server to stream sound files. WebCom does support the MIME types for Real Audio files, so anyone using a browser with the Real Audio plugin can receive streamed audio files from the WebCom server. For more information, contact Real Audio.

Real also provides information about setting up files for HTTP streaming at http://service.real.com/help/faq/index.html
