This is a quick hack from a rainy afternoon to make life easier (for birgit ;-).

Allows you to access a RIO 600. It is just a shell around rioutil from
http://rioutil.sourceforge.net/
I used version rioutil 1.2alpha

Install and try
 konqueror rio600:/

You need a working rioutil in your PATH
Again:
 rioutil -i
must work for the user who wants to use rio600.
Don't try this at home:
  I did a "chmod a+s rioutil" -- this opens a great security hole !

It display the songs and the status of the RIO 600 (info.txt).
Songs can be deleted and loaded onto the RIO 600.
