I've been playing around with making Kernow available through Java Web Start. This should be the ideal way to run Kernow as it places a shortcut on your desktop (and in your start menu in Windows) and auto-updates whenever a new version is available.
Reading around it seems Java Web Start has had mixed reviews. Personally I really like it, perhaps because I'm using Java 1.6 and Netbeans 6 M10 which makes it all pretty straightforward (auto jar-signing is really helpful in M10).
Give it a go, let me know what you think: Kernow - Java Web Start
