I agree it makes sense as a separate project.  In fact, the existing
Elephant serializer would warrant being its own project if there was
anyone interested it.  I say that not because our serializer is great,
but just because that's a highly reusable piece of code for many
purposes...and there is lots of opportunity for apply compression
technology there.

However, we can certainly but it in a "contrib" directory if nobody
wants to go through the rigamarole of creating a new project.
