Hi Neil,
Nice to hear you are making progress on multimaster
> assert(realm is None or type(realm) == six.text_type)
six.text_type means unicode.
So on python2.7, you need to use u'buildbot' for the realm config.
Thanks for your patience.
Once you got it figured out, I would love if you can contribute a
multimaster how-to.
Regards,
Pierre
