Thanks, it took a while to put it together.

I'm not sure exactly what you mean by this.  If your referring to the 
speed of JFileChooser when browsing the same SMB network share, then the 
answer is it's very fast.  If your wondering how it performs with regard 
to it's network communication profile, the answer would be not very good 
due to the inherent issues with java.io.File.

The architecture of jEdit's FSB abstracts the file system out of the 
browser, whereas JFileChooser has the file system integrated directly 
into it.  Therefore it might be difficult to accomplish this.  Also, 
based on my analysis it seems that the only thing JFileChooser *really* 
offers is the javax.swing.filechooser.FileSystemView class which is 
public and can easily be used by the jEdit FSB.
On another note, I have created a special build of "jEdit 4.2 final", 
which has all the changes that I described in my original post.  I have 
distributed it amongst the rest of the programmers in my group and 
everyone is much happier with it's performance.  If anyone would like a 
copy of the modified jEdit.jar build to experiment with, just let me know.
