No. Intrusive containers store (actually link) objects that have a
member or base hook.

boost::intrusive::list<CBaseObject> offers the same functionality as
storing pointers in a standard list. If you call:
intrusive_list.begin()->virtual_func();
You will call to virtual functions, even if the container is
boost::intrusive::list<CBaseObject>.

No. See
http://www.boost.org/doc/libs/1_35_0/doc/html/intrusive/usage_when.html
For an example where base and derived classes are stored in an intrusive
container.
