You may not be able to distribute it, but at least you will have the freedom to change and extend it for your own organisation. The reason is that they can see exactly what is going on with Linux because they have the source, and the workings of NT is hidden. I don't ever see all software becoming as free as Linux, but I think rights of owners to see and modify the source code of commercial packages will become commonplace, and that it will, in the longer run, improve the quality of that software, because users will be able to report not just bugs, but how to fix them as well. The fact that Linux is everywhere right now is very exciting. You can buy four different distributions in PC World today.
Computer magazines carry free distributions regularly.
I have seen two this week alone. Major companies are providing their core products on Linux - like Oracle 8i. In the future I think companies will begin to realise that Linux is viable for them, especially in the firewall and server markets, and that it isn't just a geek thing, it can offer real business benefits compared with the established alternatives. This is what is driving the software vendors to support it, and this reinforces the view that Linux is ready for prime time. It's a virtuous circle that will not get broken anytime soon.
