Does it require reinstallation everytime a new version or update is released or just manual application of it.
The best place to find information about updating this version is through the Community Edition forums, you can try http://www.securitywithpassion.com.au and http://efwsupport.com/
To upgrade versions, it is possible to extract RPMs from the distributed ISO images, and install/upgrade them. That will not cause you to lose configuration settings (except if Endian change the bootstrap settings) which is possible in future releases.
