     class derived : public abc

     abc * ptr = new derived;
     delete ptr;

This delete expression won't compile because abc's destructor is protected.
So it doesn't really matter whether it's virtual. For what it's worth I
don't think classes like this have enough pros to outweight their cons.
I've messed about with stuff like...

     class wibble : public interface<wibble> ...

     class fubar : public abstract<fubar>...

     class snafu : public concrete<snafu>...

These are similar, quite nice, but I still don't feel their pros outweight
their cons.
