Project is back (courtesy of Sune Alexandersen)
It's back (http://phpwebedit.sourceforge.net/demo/) now, apologies to Sune, we are using his WebExplorer (http://freshmeat.net/projects/webexplorer/) for the file system layer, but the main feature of the project is the interaction between the Java Syntax Colorizer and the file system layer.
Apparently this project has been stopped due to
An open, cross-platform journaling program.
A scientific plotting package.
