Ian Foster talks about WS-RF in an interview with Mark Baker.
Also, WS-GAF was in the news today. Not the most accurate reporting though. The reporter connected two unrelated stories. I don't think Ian Foster would have referred to WS-GAF in his teleconference. I bet he was talking about WS-RF and the reporter completely confused the two.
