The implementation relies on the cons-list implementation of tuples.
It is part of the public interface of Boost.Tuple, but not part of the  
TR1 specification.
So if one wants to define serialization so that it works with any TR1  
compatible
tuple implementation, one must build the metafunctions around the  
get<N> templates.
The downside of this is, that more compiler resources will be used.

Also, at some point we'll roll in "Fusion" that will largely replace  
the current code of
Boost.Tuple. Then we'll have more powerful means to iterate over  
tuples, in the style
of MPL. But for now, my suggestion would be to consider implement  
serialization using
TR1 compatible facilities. Or be prepared to change the implementation  
when fusion
is included into boost.
