[dwlee]

Add the zeroconf function for automatically find the concert ip.

There is a python example code: http://avahi.org/wiki/PythonBrowseExample

I also have some old python code..........somewhere, if you need, ask.

You need to look for zeroconf types: '_ros-multimaster-hub._tcp.local'

You can see our concerts on linux from the command line:

avahi-browse -t -r _ros-multimaster-hub._tcp

Make sure you do a platform check in case we try and run on windows or apple sometime.

Best way to do platform checks in python, is not to check for platform.

Instead, do import checks, e.g.:

try:
    import dbus, gobject, avahi
    # some code here
except ImportError:
   pass
