I keep getting messages about lwjgl not being present in the java.library.path, so I've decided to drop webstart. This weekend I've been investigating options. I've decided to use getdown, it's been used by others and seems to work. It's just a download/update manager really, but it's nice and customisable and a small initial install (obviously you already need java installed).

Then I looked at how to launch the thing. I've decided on a shell script for unix and a windows exe, this means I need an installer for the download/updater, so I've got izpack working. I'm not totally happy with that as it doesn't create shortcuts on anything other than windows, so I might change the installer, but the rest seems to be working.
