The problem with this is that there is no "standard java memory allocation". In my experience it differs largely between operating systems and also between Java versions. Another problem is that even if you could apply some rule of thumb (e.g.: 20 times uncompressed file size + minimum requirement for the applet) this would only apply if a single applet was started. But I would rather expect that often a user will explore several structures one after the other. And unfortunately the memory of applets whose window/tab was closed it not always released. Another problem is the applet size. Since the user can set the size freely this might also drastically change the memory required. So I would really prefer a more situation-specific solution.
