I do have a solution for the script idea. I made an executable file for windows that modifies the LimeWire listening port number. But after reading LimeWire's License Agreement, I think it would be in everyone's best interests if I do not distribute it. Unless I get a green light from a LimeWire developer, which I am not currently seeking, I am not going to release it. This type of alteration could potentially fall under the category of backwards engineering, and since LimeWire is not an opensource project, I will respect their rights and will not release any modifying software.

On the other hand, it is relatively easy for users to change the listening port themselves. It's simple enough to go to the options tab and type in a few little digits. So, if we can all coordinate our efforts, we may be able to expand the Gnutella networks should the need arise. :-)
