Yes, I'm familiar with some of those as well, and indeed one was behind the whole Ordinariate thing being pushed from the Anglican side. 

However, as someone in the Anglican Communion, I'd inform the readership of good RC folks that most of the dissident groups breaking away from either TEC or the Ch. of Eng. are majority broad to low church (evangelical). Their clergy and laity (particularly the former) want no part of tight doctrinal control from Rome, are not "Anglo-Catholic" (that group mostly swam the Tiber to Latin Rite or that "Ord" thing) and have some major issues with the office of the Pope as currently constituted.  I'd also question whether new faces are in the room or whether these breakaway groups simply rearrange the existing members either Anglican or as in the article, RC. Fresh faces from the land of the "nones" or the "dones"? I'm not convinced.

Meanwhile, the official churches are getting along with great respect. Don't let internet naysayers claim otherwise.
