There is a 64-meter parabolic steerable scope at Parkes, Australia but, gee, that's awfully small. I've heard of no concrete plans to use that scope. Maybe nothing will happen. There has been talk about making a one-square-kilometer array and putting it in Africa or Argentina. It may be in planning now. But its completion would be way off, maybe fifteen years. I don't know how much of its time would be devoted to Seti, either. I believe the One Hectare Array (maybe called the Allen scope), under construction, is in California, too far north to see much of the Southern Hemisphere. Also it's pretty small, too. I think that about four hectares of the seven-hectare Arecibo scope is in use at any one time with the Seti apparatus there - at least that's what I've heard.
