Good afternoon:

Sounds fun.

You can listen to the viewport model to detect any changes in its bounds (i.e.
the area of the wold it is displaying). You can also issue a command the
viewport to cause it to display the area of the screen you wish. The seagulls
code provides something similar where the simulation of seagulls moves points
around the screen; and you can ask the viewport to track one of them and move
the map to follow the action.

I have not tried working with a custom configuration file yet myself; just
letting it auto generate for me. I know that when you include a file in a
plugin you have to be sure to check it in the build.xml file or it will not be
wrapped up when you release your application. You may wish to look on the
internet for a tutorial on eclipse / log4g integration for an example.

You may wish to set up something in your activator to configure the log4j
system by hand; just so you can confirm it is working - and then go back to
looking into how to pass it the property file.
You may even be able to use your activator to look up the property file in the
configuration directory (which will change as it runs for each user on a
system) and pass it over to log4j.
We do something similar to look up an epsg.properties file in the
net.refractions.udig.libs plugin; as the geotools library has a similar need to
be configured prior to use.
