Porting your application to multiple distributions is a task that conjures up images of large engineering and support costs, which detract from the real value of the Linux platform. It is the primary goal of the LDN to provide the skills and the tools to vastly reduce those costs by emphasizing portability techniques for cross-distro application development, or full LSB certification.
