I'll have a look at that, thanks Robert.

Off-topic question, but when I create free-standing save/load functions for 
a class, how can I get access to that class's privates?

LOL

I'm currently doing "friend class access", but this doesn't seem to be 
enough.

Hmmm - friend class boost::serialization::access doesn't do it?

basically this is a "wrapper" which temporarily adds required information
for serialization to otherwise opaque buffers.

I've got a particular issue I cannot seem to find a solution to.

I'm using boost.serialization to deserialize audio data into an object that
wraps OpenAL. For example, the data I'm writing out would be (in order) a
single INT representing the size of the raw data and then the data buffer
after that. However, in my "Sound" object, I do not keep the data and length
information as state in the class. Instead, I just keep the OpenAL buffer
handle. In order for this class to be able to implement save(), it would
need to have extra state, which would not be appropriate. Basically, I need
to have a separate object dedicated to saving the sound data, and another
for loading it.

Is this possible? Perhaps there is a recommended design?
