Base License
The base license includes the Indicator creator applications, the relevant Indicators bytecode (packaged as jar files), full documentation of the public interfaces, demonstration code showing how to use the jar files and additional product documentation relating to the product, the demonstration applications and Indicators in general.

A base license allows you to develop and run applications based on Virtual Machinery’s Indicator classes on a single machine. You cannot distribute these applications unless you purchase a distribution license (see below).

Distribution Licenses
If you wish to distribute an application (ie install it on another machine) which uses the Indicator classes you will need a distribution license. There are three levels of distribution license -

• Site Distribution license - Allows an application which uses the Indicator classes to be installed on any number of machines on a single physically contiguous site. It also allows development of applications using the Indicator classes to take place on any of these machines.
• Corporate Distribution license - Allows an application which uses the Indicator classes to be installed on any number of machines belonging to a single corporate entity. It also allows development of applications using the Indicator classes to take place on any of these machines.
• Commercial Distribution license - Allows an application which uses the Indicator classes to be sold commercially.

In each case the Java code must be distributed as obfuscated jar files. If you are simply redistributing the Virtual Machinery jar files this is not a problem as these are already obfuscated. If you have bought the source code and modified it to suit your needs then you must obfuscate the released code. At present we only approve Retroguard (a freeware obfuscator available from Retrologic systems) but are happy to consider others provided you consult with Virtual Machinery first. You cannot distribute any of Virtual Machinery’s source code in any circumstance.

The Commercial Distribution license is required in addition to your Site, Corporate or Base license i.e. if your Corporation is developing an application at a number of different physical sites and this application is then being sold on a Commercial basis you will need both a Corporate and a Commercial Distribution license. If you are a single developer operating on just one machine and developing an application for commercial distribution then all you need is your base license and a Commercial Distribution license.

The Distribution licenses include licensed copies of the jar files. These copies do not throw up a banner on the console when they are first used.

The distribution license covers all of the base license jars and applications built with the code. This means that the purchase of the appropriate Distribution license(s) is a once off cost. All current and future Virtual Machinery Indicator products are covered by this license. This means that the cost of upgrading is reduced to that of the Base Licenses.

Source Code
You can purchase the source code to all of the Virtual Machinery Indicator products. The Java source code versions come with full Javadoc and additional documentation relating to the modification and extension of the existing classes.
