This is getting really interesting. To help clarify further -- can you give an example of the following please:

1) You are creating a base class.
2) You are not doing anything obviously wrong -- you are leaving lots of hooks and putting the properties you will need in the base class.
3) But you get yourself into real trouble and would have been much better off using composition.
