I just took a second look at at a great presentation by Johanna Kollmann on how UX designers can work well on Agile teams. I know in the teams I work with everyday, this can be a challenge. We seem to have a real problem since we have so few UX folks spread over several different Scrum teams.
Please take a look at Johanna's presentation on InfoQ.
Here is Johanna's Bio:
