Some people on your team might be tempted to record in-person user tests instead of watching them live with the idea of watching them later. I've been involved with a large number of tests, and I've never seen anyone actually go back and watch the recordings. Chances are that if someone on your team isn't motivated enough to attend the test, they aren't going to be motivated enough to watch the recording. Plus, many customers don't like the idea of being recorded.
