...BTW, in the above scenario, if "A" buys, Bill's problem is solved for a small amount. If not, then Bill needs to open the old brainbox, and do for himself what Steve did, or ask Steve how he did it, step by step. Now, if Steve had just printed the information, "Make program X work for this" with a disclaimer saying "do not redistribute... rights belong to... blabla" it would be all good, especially if he had contacted "A" prior to doing so, and let him know, and gotten an all-clear. If in doubt, ask. And always work with the preson who controls the righs- they are the last word.
