Woogley and I have been working on Playground.
Playground is a game launcher, it's currently a prototype that were trying stuff out on. It uses a central database hosted at javaunlimited.net to provide a list of categorised games which can then be launched (using JNLP but not webstart

) at the click of a button.
The prototype is still very prototype but has had a major update since last seen.
Comments and suggestions, bearing in mind this is still a prototype, appreciated.
Current the first time you use the client it'll go and grab a list of games from the central server. After this a local cache will be used - to get an updated list hit the "Update" button on the main menu.
The launching should now work on Windows, Mac and Linux.
