OpenArena, Warzone 2100, Urquan Masters, and Frozen Bubble should top your list of Linux games. Also check out Urban Terror, it is a close analog of CounterStrike.
The Wesnoth game I have never played, but am going to check it out right now
Urban Terror is great. For those that don't know about it, it uses the Quake Engine that was GPL'd. I'm also going to check out Wesnoth.
I haven't read the article, but you posting a link on slashdot proves you have a bias toward marketing.
Maybe not. I found it to be a chicken or the egg proposal. For a site designed for user contributions, such as a wiki, do you market the heck out of it, getting eyes on your site, hoping people will contribute? Or do you write furiously for months, creating content and hope others will find value and contribute their own content? Maybe a combination of both?
The article does state "Content is considered king of all techniques."
I'm betting it's not even that and it's just a heart rate monitor to improve the quality of aerobic exercise. Sounds like a pretty good program to me; if kids are going to not do physical activities willingly and do the bare minimum in gym class, monitoring heart rate might be a necessary evil to ensure they get enough exercise.
I use a HRM all the time while running or biking. Its a good way to give you feedback on your exertion level, and will allow the kids to learn more about max heart rate, threshold level etc. I would want my own band also, rather than some sopping wet band from the previous gym class. Unless they spring for the higher end moniors, the data is not downloadable and is not in any fashion similar to an EKG that would be able to determine an arrythmia.
