Hi there 
I've created an interactive tech tree web page for GalCiv2:
http://www.cosmicrealms.com/galciv2/
Simply click on a tech to expand it to the next level.
You can zoom the size of the tree by increasing or decreasing your browser font size or zoom.
Hodling control and moving the mousewheel usually does this.
The tech tree is generated live when you click directly from the XML data.
So it's up to date with the latest patches.
To use the search, just choose any fields you wish (you don't need to select them all) and hit 'Search'
Once you hit search the tech tree will auto-expands to all levels necessary to show you results.
Also the boxes will be highlighted in some manner to show you the path.
*UPDATE* The web page now supports Dark Avatar! Simply change the game type using the top left dropdown box.
Anyways, I hope people find it useful!
