[Boost-users] [serialization]-- serialize binary data to a memory buffer?

I saw an example where boost serialized a text archive to a strstream for sending via a socket. I would like to do something similar, but for binary data. Is there a way to do the binary serialization to a memory buffer, and then send it elsewhere? It doesnt seem like strstream and boost::archive::binary_oarchive would mix correctly. I have also seen some discussion regarding a binary_iostreams library, but its doesnt look like that exists yet. thanks Rich
