Lightweight volume control for XFCE?

[Christopher J. Bottaro]

Whats a good lightweight volume control for XFCE?  I'd like something 
that complies to that freedesktop standard so it will dock in the system 
tray.  Maybe something written in gtk.  I'm using FC3 btw.

On a side note, how do I make XFCE my default desktop?  I edited my 
/etc/sysconfig/desktop to have the line
DESKTOP="XFCE"
but it doesn't work.

Thanks for the help.
