Which digi cam for night time use?

It's called Nightshot on my Sony (SD-100, $1000 about 1.5 years ago) .... it works pretty decent at short range indoors but compared to actual night vision (either image intensifier tubes like night vision goggles or actual infrared cameras) it's still pretty limited. The Sony cameras, and most of the others I assume, have a infrared light and really only just dip a little into the near infrared range. It's fine for shooting movies like Paris Hilton but don't expect to see much outside on a dark night. It has a "super night shot" setting that seems to just slow the frame rate down to allow it to gather additional light but it isn't much good for anything fast moving.
