If you are using Firefox and have Java installed, you can try PWS right now in Applet mode. Just keep in mind a few things

You will not have the Firefox search-box enabled, but you can still use PWS through the Web interface.

PWS will die with its window; so keep it open while you use it.

The Applet is not properly signed, as a result you will have to accept two warning from your browser in order for the appler to run.

That said run it.
