Domain Support supports RealAudio, RealVideo, Microsoft NetShow, Vivo, and other streaming technologies through a technique known as "pseudo-streaming." This technology is compatible with RealPlayer 3.0 and higher, and all known NetShow and Vivo clients. As we use HTTP streaming to serve realaudio files, there are no limits in place on the number of concurrent streams. For information, please read our RealAudio how-to.
