Sorry, perhaps I wasn't clear enough - I haven't solved the general problem of
the serialisation of bind or function objects using boost at all - though I
would like to do the same thing.

The implementation I have is too specialised on persisting just the bits I 
need, and uses a our own persistence mechanism. I'm afraid it wouldn't be much 
of a starting point for a general solution, though I too would be very keen to 
see one.
