The simple test case would be the entire program, since it is less then
600 lines of code. But you will also need an appropriate server for it
to talk with, which I cannot provide. In addition, the application was
built on code licensed under the GPL, and posting it on a mailing list
would constitute distribution. But I cannot publish my additions under
the GPL, so rather than violate that license, I need a specific
individual email destination that will not forward it to a publicly
available location. I believe I can send it without getting a signed
NDA, since it does not reveal any confidential information.
