[Bf-committers] extension clause

A reply to the list in general, People have wanted real world cases:

The following is an example of where the GPL is being used to actively 
limit commercial use of a PHP add-on class.

Note that the GPL version is available to the general public, but to use 
it in business, you need to purchase a separate license so that your own 
code doesn't become GPL
Very clever business model, but it highlights the issue well!
