I'm the developer of Easy Decal.
I just wanted to point out quickly that it's not a "pipe dream" project.
The first stage of the application (batch decal creation) is written and working.
Myself and a few friends are using it with much satisfaction.
Also, the website is all pretty (even has a logo!), contains downloadable working releases and is ready to be seen by the public as soon as Athomas hits the 'approve' button.
The next major tasks on Easy Decal are:
1) Internationalise (/Internationalize!
) the batch processing tool.
2) Develop a GUI (over the same codebase) for decal creation.
3) Add functionality for decal installation.
4) Internationalise the GUI.
I'm of course happy to answer any questions people have about the project.
