Application Licensing

[Guest]

I've created an .Net App which I want users to be able to download from the
Web. I want to make it time-limited though and have the ability to send a
License key to them, when they purchase a copy.

Does anyone have any suggestions as to the best way to do this, either by:

(a) Using third party software, and who do you recommend?

or

(b) Programmatically...and where can I get examples for this?

Thanks

Jon

Macrovision comes to mind. I believe there are many similar products with
different licensing schemes and costs.
