Thanks! Using streambuffer or std::istringstream/std::ostringstream is indeed very convenient.
Has anyone thought about introducing default values in serialization to save the storage size (or the number of bits tranferred over network)? I hacked NVP and make_nvp to support this as an optional feature, and it works fine for me. If that sounds something might be useful to others, I can paste the patch here.
You can get these numbers by making a filter device that counts bytes, (iirc there is an example in iostreams) or by serializing to, say, a vector<char> via via one of the iostreams push_back devices and getting the container's size after the archive is closed. Serializing to a vector is also convenient if you want to, say, use boost::crc to take and transmit checksums with the data. -t
