Different things have happened, I think, but from my questions of networks in their second phase, they generally wind down fairly quickly after the end of the second phase. A lot of activities continue, which is very worthwhile, but I think it becomes difficult to maintain the tight focus on key problems, because people then seek other sources of funding--which is the norm for research people--and perhaps the other programs that they work with are not as tightly focused on a sector's key issues.
I think things begin to diffuse, and I think that's the problem. In fact, I was told by an Australian official that that's why they didn't do that, because they want to keep that focus.
