Hello. Does anybody know for certain whether it is possible or
impossible/impractical for two classes having virtual member
functions with the same name, args etc.  to use dynamic binding.

My principal concern is in the use of class libraries where
I would like to use objects of a given class in one library, say,
and also objects from another library using dynamic binding
to call a certain procedure where the actual class of the object
(one from either of the libraries) is not known at compile time.

Thanks in advance,
