Is it easy to figure out if I'll hit those conditions? Or are they 
sprinkled all around? 

I simply want to send messages through shared memory. I would like to do 
it with some type safety. The messages would be structs like so:

struct Start {...};
struct Stop {...};

typedef
   boost::variant
   <
      Start,
      Stop
   > Message;

Would raw pointers come into play? Would it depend on the contents of the 
structs?

boost::variant doesn't use virtual functions,
*but* under some conditions it can store
a raw pointer which is also a problem for
interprocess.
