Yah. And I need to write docs if I want people to use it :)

PB actually implements its own version of Pickle as well (jelly), except
that it does *not* use a whole order of magnitude more of bandwidth -
it's probably the same bandwidth usage as pickle. It's still not as fast
as it could be, but we're working on it.

Version 1.0.2 will have additional documentation.
