Object reference _narrow() question:

Will a down-casting through the reference
<reftype>::_narrow(ref) function generate net traffic?
(unless the ref is of the same as <reftype>)

Reason I ask, is that I'm implementing a data-pushing
mechanism where it’s convenient to store only references of
the base class, but to push data to a more specialised class
– thus needing to down-cast.
As always – alas – the communication rate is limited.
