Hi,
I have developed some rather nifty auction software, it's taken me ages and I want to distribute and sell it over the internet. I'm happy for people to download and install it themselves, but then I want to ensure that they pay me for using the software. What is the best way of doing this?

Is the best way to provide the software free, then provide a license key upon payment being recieved. If a license key isn't entered then the software shows a big 'THIS SOFTWARE IS NOT LICENSED' message across the users screen.

How can I implement this when all the code is totally viewable by the person who downloads it? I want to ensure they can't just hack the code and take out the 'THIS SOFTWARE IS NOT LICENSED' message.... is there any way to encrypt the Perl code (you can do this with PHP code)?

Your thoughts on this matter would be very much appreciated!

Thanks,
Tom
