When you upgrade to Fedora 9, make sure you get the zero-day update of icedtea/openjdk that Lillian made. It includes some sound fixes, Gervill midi support, the hat tool and fixes for javaws/netx. Then try out Jake2 (GPLed Quake engine in Java using Jogl and Joal). Just click that Jake2 webstart link, it will just work out of the box. Awesome!
