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.
