Yes. There is actually some paper being done for the G-8 meeting that I'd be happy to forward to you. It has a summary.
The two issues that are most obvious are, one, it's not clear that foundations can invest in limited partnerships, and many foundations that are the first actors in this area—again, to quote James, and I would agree—are stymied by that. Two, there is some ambiguity about whether non-profits can really build a balance sheet without suffering some additional scrutiny and tension with the CRA.
