Sun Microsystems's versatile Java Web Start mechanism helps ensure that users always have the latest features. The application is digitally signed, ensuring that the downloaded application hasn't been tampered with. This mechanism offers the ease of access of a web page, and the rich capabilities and integration of a true desktop application. After the initial Java install of about 15MB (distributable via CD), the application download is about half a MB, preventing the need for long download times for each application update. Labs with large product listings can zip their templates file, further decreasing the time needed for studios to download and get started.
