Bwahahaha, that's awesome. There's an apartment complex near my house that does something like this. It has a manicured rocky slope leading from the courtyard down to heavily used bike/foot trail (Centennial Trail). They have some nice stairs leading down to said trail and, to keep out the riff-raff, about a three-foot gate with a combination lock on it. Not only is the gate easily jumpable, but the rocks on either side are easily climbable.<p>Security for the win!
The picture kind of fails to capture the idea that people's common sense notions seem to come to a screaming halt whenever computers are involved - no one in their right mind would believe doing things that way makes for a secure home, but it's easy to get people to believe all manner of things with respect to computing.
