InstallAware

I realise this is off topic but I've been playing with the installer passwords and the finger printing the application.

What are other people using to "copy protect" their .NET and C/C++ apps in addition to these methods.

For full apps I tend to use online activation (along with a method of manually skipping it using a watermarked update), but for Assemblies / DLL's I tend to just use a trust based registration code.

Unfortunately registration is always a tricky balance of convenience and effectiveness.
