Flattening is not specific to message sending, just data structures in
general. Over the years I have developed several protocol applications,
some serial I/O, some network packets and I recognized what he trying to
do. The principles of layering your message fragments so you deal with
one abstraction at a time is common. It is also a fascinating area in
which to use Python's introspection and metadata capabilities to greatly
simplify something that is rather complicated when written in a
procedural language like C. See my next email for an example.

You're probably right but I thought the docs for STAN were well-written
and would be useful reading at least. STAN itself is actually a small
part of Twisted, about 25 KB of source. I just happened to be reading
the source earlier this week as I was trying to use it as an alternative
template language with the Grok web framework. It won't just drop into
Grok because of Twisted's way of using zope.interface and their own
adapter registry. Therefore I'm working to split STAN out as a separate
egg usable with Grok. I wish the Twisted folk would cooperate better
with the setuptools world.
