This is the same approach we've taken with candidates. We start with a phone screen and then a simple coding problem submitted via email. When we bring them in for an interview they spend time with with a few developers working collaboratively on a problem. If possible, it's a bit of work from the current iteration. Working together on real-world code has been surprisingly effective. I was skeptical at first, but it has been very helpful in weeding out candidates who had good cv's and probably could have coded a really great algorithm to traverse a binary tree but weren't great with solving real world problems.
