That is a single system. iPhone...not going to happen until the license changes,
and unlike SuperWaba, I don't feel I can force folks to jail break their phone,
but too, that gets into legal world. Most regular application users don't even
know what that means.

Yes and no on the store. You as a person who knows Java thinks...Java store. The
person on a BB, iPhone, or Droid, thinks, hmmm...I use the BB app store, or
apple app store, etc which is right there on their phone with no external setup.
It is all about customer expectations and marketing etc. Hard to have 2 stores
in reality. Now, they could work with the other companies perhaps to make it
happen. Then they could have the Java store which transparent to the user sells
those same apps through those specific app stores. They could use such a thing
to help pay for it.

But doesn't that all depend on an implementation of the JVM for the device you
are using? Too, what if it is a more advanced phone offering their own APIs such
as Black Berry? My storm has some apps I have put on it that just don't look
great unless they use the right APIs. The plain jane JME applications don't
