Matthias,
Most companies abide by a simple formula:
work = time = money
So, in order to justify Apple to use resources in order to implement the
JSR-82, a clear business case needs to made. In other words, will more
people make "the switch" if Apple had a really cool Bluetooth platform?
Will people find it cool that they can transfer their JSR-82 game from
their phone to their iBook and play it there? Will developers create
more apps that used Bluetooth to communicate between PDAs and desktops
if they could use the same langauge on both platforms?
And yes, a J2ME implementation is required to pass the JSR-82 TCK
(technology compatibility kit). You can use the CLDC or the CDC (they
are both J2ME).
Now, the JSR-82 license has an important clause that I've noticed. You
have to pay a royalty fee to Motorola only if you sell your JSR-82
implementation. So essentially, if Apple implemented the JSR-82 and gave
away the SDK, they they wouldn't have to pay Motorola a dime. :-)

Hello Bruce.
browsing to the list of issues considering an JSR-82 implementation I
would state that:
1. implementing the spec
requires "just" work
3. creating a J2ME KVM for OS X
I'm not sure it this is required. I could think of a JSR-82 compliant
classes for J2SE.
4. integrating the Bluetooth libraries with the KVM
Similar to 3.
2. obtaining a license from Motorola (Motorola owns the rights to
license the spec)
This seems to me as the most critical point. I'm not sure if your
right with this.
I couldn't find any explicit statement that says I would have to get
a license to
implement jsr82.
On motorolas page:
http://e-www.motorola.com/webapp/sps/
siteprod_summary.jsp?code=JAVA+APIS+FOR+BLUETOOTH+V.1.0&nodeId=01J4Fs8X9
F
It says that I can license their reference implementation and a java vm.
To me it looked like everybody could implement that standard api
(to me this is an important point about a standard.. :)
maybe someone could comment on the legal issues.
apple?
