[Mono-list] Mapping between CLR virtual table and C++ virtual table

How does one use this mapping with Mono? Do the C++ classes involved have to 
be specially compiled, or is it possible to override the C++ virtual method 
table at runtime for an ordinary, already-compiled C++ class? If so, how do I 
use this capability? I saw some postings about virtual methods table hacking 
about 9 months ago, but they seemed to be related to embedding Mono into a 
C++ program rather than the situation we have with Qt#.
