I've read a little about them back when I was an Episcopalian (ECUSA). Lev Gillette, the Orthodox writer was a founding member. I'm not sure they can do any serious work given the radical changes in the Anglican Communion. Any chance of communion between Anglicans & Orthodoxy went out the window with the ordination of women in the 1970's.
Some other trends that would probably throw a wrench in the works are the movement towards lay presidency at the Eucharist (in Australia) the number of American Episcopal priests who participate in pro-abortion activities, the blessings of sam e-sex unions in many American and Canadian parishes, the metamorphisis of 'open Communion" (1970's-"any baptised Christian who truly wishes to receive the Body and Blood of Christ" 1980's-"any baptised Christian" 2000's-many parish websites happily invite anyone, baptised or not to receive) the inclusion of non-Christian religious leaders in ECUSA ceremonies.
Gee, I just realized, many of these things helped me decide to become Orthodox!
