I used BOOST_FUSION_ADAPT_STRUCT in conjuction with boost.serialization to
automate serialization of messages between clients and server in my
application. It just reflects simple C++ structs with data to XML/TEXT for
pass them throughout network.
After few experiments with RTTI, some kind of type erasure (with "variant"
and
"any" types), true object-oriented approach and boost.fusion I have found
that
the last one gives more benefits and fit in static type system of C++ more
naturally.

As alternate you look at implementation of serialization in
Different ORM libraries, but they use external tools
Message passing and RMI libraries like Apache.Thief or libcppa, but they use
RTTI AFAIK.

I think boost.fusion is the only one way to implement true compile-time
reflection. With certain restrictions, of course.
