When I started implementing LuaSocket 2.0, I had this delusion of making
all modules (udp, tcp, file, pipe, local etc, even http, ftp etc)
dynamically loadable by LuaSocket, just as now luasocket and other
libraries can be loaded dynamically by Lua. The support is all there for
that, and this is why I wrote the auxiliar.[ch] module. Modules written
by other people would use the interface as a mini luasocket C API. It
was part of my delusion that people would write modules for
serial/parallel port communication, named pipes, ssl and whatever else
they could come up with. :o)

The input buffering module and the IO abstraction are there to try help
implementors of other modules to preserve the look and feel of
LuaSocket.  I am (was) planning to write a section on the manual about
how to extend luasocket and that section would cover all the modules in
the implementation. Instead, I wrote about it in the header files (did
you check auxiliar.h, buffer.h, io.h etc?).

I would be very happy to help you write a module (like mbus.c, say) that
would be compatible with LuaSocket. I would help you out with the
integration details that you might need, of course, since I am not
familiar with MBUS.

Thanks! It is the result of at least 3 rewrites (over more than one
year) since LuaSocket 1.4, and in the redesign process I was lucky to
have the help of Carlos Cassino.
