Hi, My colleague asked me a question like "license check to config file".

when i searched i got this

http://www.google.com/search?q=file+verification+system&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a

and in the result i got this http://integrit.sourceforge.net/texinfo/integrit.html but could not grasp much of its idea.

Here is my thoughts...

Our project is written in codeigniter. The project owner is providing it to their customer. The owner is a business partner with that concept. Besides, the owner needs control of the project code so that the customer will not break rules with him like changing the code or moving it go another server or validity.

So the owner needs a system to enable disable the site. Let me give an example...

owner.com will have an admin panel where he can either disable or enable the client.com.

when he disables the client.com should display a custom message instead of loading the files.

client.com is written i a way that i will process requests from owner.com and also the other way round.

so, here i want a list of the concepts with which we can implement the ownership and control over client.com

any suggestions, links, references, answers will be helpful.

If i am missing something in my question i will update my question according to your comments if any so that the users can give in their idea without confusing of what i had asked.

THX
