Hi,
I am considering a diagramming application as a plug-in for Inkscape, and would need to do it in Java. Using Inkscape as the canvas seems to be a very compelling concept, but I would like to get this confirmed.

To make it interactive, it must hook up with Inkscape, are there sufficient possibilities from plain Java?
Is there already some Java plug-in that could serve as a template?

The result would be open sourced. Thanks for any pointers.

You may get more response on the Inkscape developers' mailing list (if you haven't already). Here's a link:

Thanks for that pointer I found it hard to get the information I need from on-line
