DBus Instructions

In Terminal,
dbus-daemon --fork --print-address --session

Copy the mess, and set environment variable
DBUS_SESSION_BUS_ADDRESS
to that:

for OSX in Terminal: (for both tabs - python and lisp!)
export DBUS_SESSION_BUS_ADDRESS="unix:path=/tmp/dbus-TPB6otEYhX,guid=64541960e7c06df645501f00474339c6"

don't need this in lisp after all:
(require :sb-posix)
(sb-posix:putenv "DBUS_SESSION_BUS_ADDRESS=unix:path=/tmp/dbus-ATsZEbyMym,guid=7658085a86260c15efea5b0047c9f80c")

set environment variable for OSX in Terminal:
export DBUS_SESSION_BUS_ADDRESS="unix:path=/tmp/dbus-TPB6otEYhX,guid=64541960e7c06df645501f00474339c6"


need to run python from command line - specifically, /opt/local/bin/python2.4

sbcl --load load-act-r-6.lisp

main.lisp
prints out all names visible on the bus (prototype client)

service.lisp
offers service (prototype - doesn't yet handle introspection)

test.py
interfaces with service in service.lisp
currently takes 60 seconds to wait for introspection error to timeout
prints "Hello World"

**Why not use TCP/IP?
Serialization
CL-JSON
Javascript object notation

Mike Byrne is on record saying that UDP packets sometimes just disappear

Structuring services
synchronization problems with Python (no threads!)

Reusability and modularization
Language neutral published standard, only need to do it once
