Avaya's New Zang.io

I am interested to see how this new offering from Avaya called Zang.io will work out.  I have seen it used in the Enterprise Connect Hack-a-Thon, but I am curious how real customers will use it.  I will need to follow up on this.  Avaya is really trying to make a comeback, but it may be a bit late.  We will see.
