If you have software in front of you that is protected under the LBDT-License, you are only allowed to do certain things:
HOWEVER, in Version 2.0, there is an exception clause:
A functional use license may be granted upon payment to the owner of the software. Such payments are subject to prior negotiation and will depend on the complexity and scope of the software in question. No offers, payments or assumptions of rights are valid unless expressly agreed to in writing by the author in advance.
