Hi Oono-san,

I'm forwarding your e-mail questions to the mailing list
(advanced@phoneme.dev.java.net) since as you guessed that is the correct
place to post your questions so that others in the project may help
answer your questions and in the future others will see the answers.

Some answers below...

Do you mean being able to turn off softfloat support and use a hardware
floating point solution?

There is no plan yet for the MR2 release, but we'll let you know when we
find out from our marketing and management what the plan will be.

I'm not aware of pMEA MR2 being officially ported to those platforms,
only proof-of-concepts so far and nothing official. pMEA MR2 b97 is
reliable and has been tested, but only on Linux/x86 so far.

Yes, please post any suggestions you have pMEA and we can discuss this
further on the pMEA forum and help prioritize with others.

Thanks,

Thank you for your consideration of this matter.
I'm a little concerned about the decreasing numbers of mail posted to
advanced@phoneme.dev.java.net.
In contrast, more active discussions are held in the forum "phoneME
Advanced software".

Yes, and we want to utilize the hardware capability.
CPU such as Pentium/x86 has built-in FPU.

Got it. I look forward to hearing from you.
I wouldn't like to think that commercial license JavaVM "JavaME/CDC"
have no small effect on this matter.

I built up my expectations by looking at your presentation material
for JavaOne2008.

I understood the current conditions porting pMEA MR2.
How about pMEA MR1 or pMEF?

Additionally, please tell us if there is any technical problem that needs to be
solved when we officially use pMEA MR2 b97 on our product of Linux/x86?
Naturally we must conform to GNU GPL of pMEA.

Is there a way to know current status of each item in the to-do list?

Best regards.
