[Boost-users] Re: Serialization of heterogeneous sequence usingshared_ptr<void>

boost::variant serialization is implemented in the next version (1.32) that
might work. If you want to make an implementation of boost::any
serialization that might work too.

In fact I think the way to go about this is to decide which of the above
suits you best and if it doesn't implement serialization, do it yourself!
