Yes, I see. I did however like the idea of having it at streambuf or stream 
level as I know how many bytes are in the stream. This I had in mind earlier also.

Perhaps in betterness, but the lower you get, lesser the info. On the archive 
level, it would be possible to also include names of classes/members being 
serialized. But progress info will be sufficient.

What I do is something like this:

A a;
boost::archive::xml_iarchive ia(stream);
ia >> boost::serialization::make_nvp("xmldoc", A);

where stream is std::istream& . I'm not sure where to hook into the stream (I'm 
no STL lowlevel expert). Should I make my own streambuf implementation?

TIA
