JavaViewer VNC Development

[thetechteacher]

Am I missing it somewhere?
Is there a "one repository to rule them all" of the JavaViewer VNC source?
UltraVNC has code in it's SVN and it's CVS, TightVNC has code in it's SVN and it's CVS, RealVNC lets you download code, etc. etc.

I know there is no single JavaViewer VNC repo because they all have different features/customizations. BUT, they are all from the same base. Which is the "standard" (Java) project? Do common changes get sent back to one? Is there any sharing? Is there even any development?

Why I care: I'm working on a java project that embeds a VNC Viewer inside of it, and I want to contribute back the few bugs I've found and, of course, I want to be able to use future developments from any of the projects.

I know BuggyBunny has expressed an interest in working with the Java code:

The README file with the Java code from UltraVNC reads: "As soon as this new JavaViewer reaches the 'beta' stage we'll put the source code in UltraVNC CVS repository."
Additionally, amongst the many VNC mailinglists there are occasional bug fixes people post.
Is there a single place I should be starting from?

Ideally, I would like to be able use and share with all different VNC flavors.

THANKS.
