The reason I would never support a hacker passport is that it would involve me refusing hacker guests who don't possess one.<br><br>Seriously, unless someone is going to be in my space, consuming its resources at the expense of my membership for several weeks, I don't see any problem with a completely informal system. If a visiting hacker will require the resources of my space in that way, we'll work out an ad hoc agreement. It certainly doesn't happen often enough to be a systematic problem requiring a systematic solution.<br>
<br>Rules are bad; we only need them when the problems are worse. As such I rejoyce at the idea that hackers cooperate on the basis of being intelligent people rather than participants in a system.<br>
