      Actually, Debian Linux (what Ubuntu was based off of when it started) has had PPC support since the 1990's.

      Ubuntu has Alternate boot CD images for PPC for both Server and Desktop versions...

      From: http://cdimage.ubuntu.com/ports/releases/9.04/release/

      Alternate install CD
      The alternate install CD allows you to perform certain specialist installations of Ubuntu. It provides for the following situations:
      • setting up automated deployments;
      • upgrading from older installations without network access;
      • LVM and/or RAID partitioning;
      • installs on systems with less than about 256MB of RAM (although note that low-memory systems may not be able to run a full desktop environment reasonably).
      In the event that you encounter a bug using the alternate installer, please file a bug on the debian-installer package.
      There are six images available, each for a different type of computer:
      Mac (PowerPC) and IBM-PPC (POWER5) alternate install CD
      For Apple Macintosh G3, G4, and G5 computers, including iBooks and PowerBooks as well as IBM OpenPower machines.

      Of course, getting Sun's Java JVM to run on those used to be a "rare treat". Having not tried in a long time, I Googled...

      Looks like according to this, it's supported... sun-java6-bin package from the Universe repository...

      From: https://help.ubuntu.com/community/Java

      To get Sun Java under Ubuntu 7.04 or later running on Intel or PowerPC platform, you should enable the Universe repository in Add/Remove programs, and install either the openjdk-6-jre package or the sun-java6-bin package. (Note: PowerPC version is slow).

      I bet if the developers call it "slow", it likely won't perform well doing real-time audio packet encoding/decoding. I wouldn't expect (especially considering his comments already stated) that Robin should support it in any way. Probably best to let that sleeping dog lie.

      But... it just might be a "if you can roll your own that far and get it working, great... if not, no harm, no foul" type of situation like most things where Linux meets Java... it's gotten better over the years, as Robin's products using it can attest, but frankly I'm amazed the he supports the mess that Linux created for audio drivers at all... Linux audio is a nightmare of bad design...

      Also, I should mention that to some extent Java on Linux was painful right up until Sun started pushing their own i386 hardware platforms. Prior to that, the best way to run Java was Windows x86 or Sparc processor-based machines. That was a long time ago, though. At least THAT got worked out.

      So, Robin for sure knows what works and what doesn't with DVTool, but the "platform" of PPC/Linux + Sun Java DOES exist... I can imagine the internals of DVTool must already be quite "interesting" to support all the platforms Robin already supports, unless the JVM is handling all that "magic" for him. I doubt it's that simple, though... Java never is... even though it purported to make all that stuff "just work" on wildly different hardware, since the day it was first released...
