The difference between the plugin and factory is that the plug is cofiguration driven. But Factory is code driven. In a factory you normally have a condition statement that decide which instance to create.

Why reply to something that is more than a year old?
And BTW I am not even so sure the answer is 100% correct. Factories
can use configuration files. And plugins can be auto detected instead
of being configured. The main difference must be the level: plugins
are larger chunks of code that are used by an application, factory is
a single class that return instances of classes.
