The first public release - 1.0a1 - of VG Sudoku is a fact!
Both an executable JAR and a source .z are available!
Enjoy! (and please tell me what you think!)
I have just uploaded the source on SVN. If you have Eclipse and Subclipse you can directly checkout the Eclipse project from https://vg-sudoku.svn.sourceforge.net/svnroot/vg-sudoku/eclipse-project/trunk.
