is there a Java VM for NV+

I was wondering if anyone has tried compiling IcedTea for NV+ It is meant to be totally open source so should be possible ? Even if it is using zero interpreter (i.e. no JIT), it would be better than nothing.

Open Source does not neccessarily mean architecture independent. Even if it's written in some high level language like c++ the sourcecode is not neccessarily portable to different architectures by simply compiling it for that architecture.
It might be possible to extract the concepts and adapt them to the different environment though. This is likely to be a lifetime task for any normal person. Especially since we are talking about rebuilding a complete virtual abstraction layer between the system and the java bytecode.

It seems that there are instructions for Sparc on Gento Linux which may be useful here. Their method requires someone getting Portage scripts working on Debian Linux first. Here are some links if someone wants to get things started (It is probably beyond my ability, but I think I will give things a go using the Sparc QEMU image) http://en.gentoo-wiki.com/wiki/Java_on_SPARC Info about trying to get Portage on other linux systems is here : http://forums.gentoo.org/viewtopic.php?t=125553

Not sure what they are referring to in this case, but keep in mind there are 2 very different sparc architectures around.
What is commonly referred to as Sparc nowadays is the late 64 bit sparc based processors like they were used in Sun Workstations.
In the Sparc ReadyNAS systems you can find a processor based on the 32 bit Sparc architecture.
The Processors in the NAS systems are compact and adapted versions of the processors that Sun built from 1992-1995 (V8 generation).
Debian discontinued support for these and even most of the newer Sparc processors that were introduced until 2007 in version 4. (Read: Debian 3 Sarge was the last Debian that had active support for the processor used on the NAS)
Most of the packages that come with the Radiator Firmware are custom built by Infrant or Netgear and thus more current than what is available from standard debian repositories.

As far as I know, the Gentoo project does not currently maintain a version for the V8 generation Sparc processors. That means your links are referring to a newer Sparc architecture not compatible with the processor used in our NAS boxes.
