Take a look here: http://sharewarestarterkit.com/Default.aspx
Or if you want to create your own solution; you can create a math's function to uses a MAC address, some key built into your application, and a key only you know (like a PKI pair). Then once the value has been calculated, the user can enter that as a code.Then
the applciation is unlocked. You can also get you application to check everytime it starts, or a function is run.
Then all you need to do is work on a method to get the code to the user. YOu could use a web service and get the application to check that service every 30 days. etc

I don't have any code on hand. I would create a hashed file using some form of PKI. You application would have the code to unhash the file and check the details. Inside that file you can hold any information you want, like number of seats etc.
