From the complete article:
"Got a hankering for some remote viewing of YouTube goodies or some radio streaming? Well then, RSS Streaming Tools may be the app you need. RSS Streaming Tools allows users to listen to their computer's mp3 playlists or streamable radio stations, as well as download YouTube vids off the net directly onto the PSP.
According to the Sven Nobis, the app's developer RSS Streaming Tools is currently a public alpha with most of the functions working, except for the following:
-Create Playlists on PSP
-In PSPWirelessMusic: Import/Export, New Channel -> Wizard
To get this app to work, you'll need WLan on your computer and a PSP. Just run the application on your computer and follow the rest of the directions given in the installation procedure for the apps to work with your PSP. For now, we'll leave you with a sample of what RSS Streaming Tools can do by showing you a video of the functions in action."

Although the embedded video may initially appear obscure and irrelevant, my impression is that the creator is successfully attempting to demonstrate audio streaming from the PC to the PSP.
