StreamToMe is an app for Windows, Mac OSX, and iOS that lets you stream music and video files (in a wide variety of formats) live from another computer.
StreamToMe requires its accompaniment, ServeToMe, to be installed on your desktop computer.
Music and video do not need to be pre-converted to an iPhone size or format — the ServeToMe application converts files to a friendly format on-the-fly, so a single touch will start playback in as little as 5 seconds. It can play a huge range of video and music formats including MP4, AVI, MOV, FLV, MPG, MKV, MP3, AAC, WMA and WMV formats. More Info »
