Sure.  You'll need at least one parameter, the URL, and I'd want to let
you do a whole bunch of registers (possibly with namespace) and then a
serve_forever ...  But that basic thing is no problem.  I assume you
don't care if it's built on python's httpserver.

Somewhat flip answer: without external schema information you don't know
that the order matters. If you do know that the order matters, then do
it Right (sic :) and use typecodes.

Real answer:  SOAP encoding says that within a struct order does not
matter, only names. So if there's an implementation that is using
gensym'd names (I use id() myself) and requiring its recipients to know
the order, that implementation is wrong.

Order *does* matter for arrays, of course, and ZSI does them as python
lists.
