Bad, bad idea.  For this to be guaranteed to work, you could never 
upgrade your compiler version or change compilers.  You can't even 
change some compiler options even if you were willing to stick with a 
single compiler, because there are options that will change the binary 
layout of your classes.

Do a Google search for object serialization in C++.  There are ways to 
get around this problem, many of which will solve the BLOB problem as a 
side effect.

Or, switch to a language that understands things like serialization and 
reflection.  This is one of the things that C++ is just not good at.
