I wrote some software to analyze DAMA channel utilization several years ago. Even got a boondoggle business trip to Hawaii and Guam* out of the deal.

Here's a link to UFO.

* Actually, the trip was damned tiring, especially the trip home. I woke at 4 AM in Guam, returned my rental car, and checked in at the airport. We took off a couple hours later and flew to Tokyo where I had an 8 hour layover. The good part is that Northwest put me up in a hotel so I could get a bit of sleep. After that, we flew for many butt-numbing hours to get to Minneapolis where I had an even longer layover before catching a flight to Colorado Springs. From the time I woke up in Guam until I got home, some 33 hours went by, and due to the date line, it was all on a Thursday. That was truly my "longest day."
