Applets issue - 32bit browsers and 64bit JVM

This is certainly a problem we want to address. It's not new, nor is it even specific to FX applets/web start applications. In the past it hasn't been as big a problem as most 64 bit systems still had 32 bit browsers.
We believe we can address this by supplying a more universal "plugin" that can launch the app using either a 32 bit of 64 bit JRE. It's significantly simpler for webstart, but theoretically possible for applets as well. Then users only have one JRE installed, and we can launch the app regardless of which one they've installed.
There is a grey area that requires more thought -- what about applications that depend on native code? How can we make specifying both platform-specific an chip arch-specific native extensions practical?
