after a long long time i just managed to get released a new version of the CD-ROM webserver 
Server2Go.
The reason for the long development time was that I had a lot of other things to do that need my attention. The deadline of my symfony book and I hold some workshops for PHP and Symfony. But the book is done so I have more time for Server2Go in the near future, so i hopefully can release a new version more often.   
But now what is new in the version 1.6.0:
    *  PHP Update to 5.2.6
    * Improved Proxy override
    * Update Apache to 2.2.6
    * Update Apache to 2.0.61
    * Allows encryption of database in source folder
    * Support for portable firefox (see 
wiki for more information on how to do)
    * The shutdown message is customisable
Hope you like it!
