Java Programming

Hi guys (and girls of course)

I have been working on a new network-administrator tool and really need the feedback of the Java community, because who
better to ask for advice then the people that can actually point out my mistakes. :)

The application is meant to make the job of network-administrators easier and faster.
The ultimate goal of the application is to map out an entire network into an easy to view visual device- and connection-map.
All devices and computers can be manipulated, including adding/removing hardware and software, and specific network
information can be added to each device.

The main features include
- Drag'n'Drop device onto the network
- Move devices and connect devices to each others
- Add/remove hardware(like motherboard, CPU, ram, etc)
- Add/remove software(like OS, antivirus, etc)
- (New!) Network specific Rules
- Export any network as an Image(png, jpg)

The application is written entirely in pure java, uses no database and works as a standalone application on all operating systems that can run JRE 1.6.
It also uses a Netbeans library(API.Visual) for the canvas function, for which I am very grateful to the NetBeans project.

The application comes with a java installer that should let one installer do the job for all the platforms(!), but that is being tested out right now so
don't shot if it gives an error. There is also an non-installer versions of the application, which only need extraction into any folder.

I really would appreciate any and all feedback, good or bad.
