The Personal Edition will be free, and will only support connections from the local machine, so it will be completely isolated from all other computers on the LAN and on the Internet. After installing, you'll point your browser to "http://localhost/QDL" to access the local installation. Anybody else going to "localhost" will access their installations of QDL (if they have them), not yours. Attempts to connect from other machines using IP addresses will be rejected, so only connections explicitly specifying "localhost" will get a response from QDL.

 

The Personal Edition will have all of the features of the Corporate Edition, so it will be great for users who simply want to master QDL, as well as developers who want to build and test applications based on QDL.
