I've just bundled up the ALOHA application (version 1.3) as a MacOSX bundle, so you don't have to go through Java Web Start to fire it up. The other added bonus is that it looks more like a "native" application, using the real live menu bar and everything!
Here's a link to the disk image containing the application. The bundling was absolutely trival. Just fire up Jar Bundler, feed it the .jar(s) and configure it a bit. Done.
