161165 Block programs and websites

I need a program designed similar to this one: [login to view URL] It is a program to help users get more work done by blocking certain applications on their computers that they check off the list. These programs can be blocked for a certain number of hours and/or minutes and can only be unblocked by typing in a long 32-character random key. Programs can be added and deleted from the list, and profiles can be created (i.e. for different users of a single computer) to save which programs should be blocked and for how long. I need an application that does everything this one does, only with two changes: 1) I would like the application to be able to block websites too. This can be done by editing the user's HOSTS file... see [login to view URL] - there should be some default websites, but users should be able to custom-add websites to block, remove websites from the list, etc. Maybe this could be done in a second frame to the right of the program list frame. 2) The interface needs to be switched around a little bit so the interface isn't a direct copy. The original program IS under the GPL, but I do NOT want the source code from it to be used because that would force me to have this new program be under the GPL license. This new program should run on Windows 98 and up. (Including Vista) So, no .NET, sorry. Also, I would like a Nullsoft installer for the new program ([login to view URL]) Thanks for your time!
