The issue with the plugin is having a browser that matches your JRE. The new browser plugin technology in JavaSE 6 update 10 suggests a solution. Since the JRE is now run out of process the VM and the browser don't have to match. A 32bit browser could use either a 32bit VM or 64bit VM, and vice versa. I suspect this is the route we will take going forward.
