Can you "catch" an Achievement?

I love achievements. I think it's the single most effective way to pokemonetize Xbox Live. But how many clever ways can developers come up with to make it challenging to earn an achievement.

Well, at least one more. Turns out the upcoming Xbox Live Arcade title Small Arms will have an achievement that is, for lack of a better word, viral. At first, only the four developers at Gastronaut (the title's developers" will have the achievement. The only way to earn the achivement is to play with someone who has it already, which means playing with someone at Gastronaut, or playing with someone who's played with someone at Gastronaut, or ... you get the point.

It's like Six Degrees of Xbox Live Arcade.
