Not sure if this has progressed any lately but I would be interested.
I know of several projects in Java already that may be used/modified to work in an automotive environment, for example;
http://www.javazoom.net/index.shtml
This is an mp3 player that is like WinAMP written in Java
I believe there are some projects for embedding MPlayer in java
There is also an elmscan app in java (not sure of the link)
As for GPS i had a thought of using shape files as the map data (see
http://www.census.gov/geo/www/tiger/...tgr2006se.html) the US Census publishes all of the USGS data here for free.
Not sure if these are available for other countries but they should be...
There are a few projects for reading them that might work as well;
http://openmap.bbn.com/
There are also a few GIS tool kits(libraries) for Java.
I think I even saw a project which connects to a map server and downloads map images (regular or satellite) and then re-builds the images as a map as you navigate around.
Not to mention any other app you can think of.
I think there a few of us here that are developing our own Java front-end, how about collaborating together on a project?
I like the idea of having an "Add-in" system capable of launching any jar file as well as native apps (though that might be more difficult).
We may be able to use some of the technology used in
http://jdx.sourceforge.net/ (A Java X manager)
or even
http://www.sun.com/software/javadesktopsystem/
and there is also
http://www.sun.com/software/looking_glass/ but I think that would be too processor intensive for a carPC environment.
There are a lot of resources out there that I think could be adapted to the CarPC world, if we could get a project going we could make some progress.
just my thoughts,
