I am curious ? Is this even legal ? After all that hallabaloo about Napster and electronic trading of media, can we sell, trade or even give away "software" ., even if we buy it ? For example, I have an old copy of Sonic Foundry Sound Forge 4.5 that I purchased. I recently purchased Sound Forge 5.0, now I no longer need 4.5, can I sell that ? Or trade it, if so what's the difference between that and trading on Napster (except that Napster has 1,000's of people trading 100,000's of files, and I have just 1 Sound Forge 4.5). Does the volume of the trade matter, or is it the principle of it all?
