Update 2013 : Some of the ideas from SdiDesk have migrated into OWL OutlinerWithWikiLinking
Update: March 2012
I am no longer thinking of developing a new SdiDesk. Instead I've decided to re-orient all my wiki-tool development projects around the ProjectThoughtStorms.
Sep 2008, I've had someone convert to VB.NET ... source-code of work-in-progress currently at http://code.google.com/p/sdidesk/
I'm very soft launching the prototype of a program I've been working on for the last few months. It's basically a desktop application which acts very like this wiki. You can use it for quick note-taking, HyperText authoring.
It has a couple of cool features that this wiki has :
full text search
And a couple of things it doesn't
coloured "typed" links (TypingNotClassifying)
a simple network sketching mode. See AboutSdiDeskNetworks
But note, it's very much a prototype / draft / UnfinishedProject which I'm shipping to get feedback. And it's written in VB so it's Windows only. It might not even work on your configuration, but I don't have a lot of machines to try it on. It works on the Windows 98 machines I have available, but I don't know where else. All bug reports gratefully received.
Oh, and it's GPLed, so if you have a copy of VB, you can get going on the source code.
If interested go over to for http://www.nooranch.com/sdidesk/wiki/wiki.cgi for more details.
Maybe it should spit out GraphML
