Why not? What prevents Oracle from compiling a JVM for RIM Playbook OS
and offer it for download from Java.com?. Vendors can just pacakge
app-installers that check if the JVM is present on the device and if

Abonut J2ME apps, cross-platform works, I run Google´s GMail Java ME
app on my Palm Centro, even while it isn´t a supported configuration.
It just works.
What I envision is being able to click on a ".jad" http:// link on a
tablet browser, and (after the Java VM is configured as helper app)
the OS offering me to run the mobile app as a desktop widget on the
