Let me get this straight - you want to enforce whether or not I have installed your libraries on two front-end servers vs. one. What if they're a pool serving the same website? What if I run more than one website on the same server? How do you license that?!? More importantly, even with protection of library and the like, how do you enforce that?

Also, you're talking about compiling and the like. Well, that has never stopped consulting firms from giving their consultants free copies of Windows 2000 or Visual Studio, Professional Edition. (I know several people who have received both for free.) Now, those people can never call up Microsoft and receive support for those products, nor can they receive free or reduced-price updates. (They shouldn't be able to receive bugfixes, but Microsoft apparently lets bootleg copies be patched.) How are you going to do better than Microsoft in the licensing arena?

If you're not going to trust your client to some minimal degree, don't do business with them. I mean, they might not pay you and then you'd be up a smelly creek without a paddle, wouldn't you?
