Not practicable in Germany. A few weeks and the police would raid the hacker space and take everything that looks like a computer (for a very broad definition of computer) with them. End of hacker space - even if your equippment is returned (which happens usually after 6+ months) when the charges are dropped.

Haha, as if we didn't get enough folks coming around wanting to hack the gibson! But really, the challenges around retaking the hacker term to mean tinkerer/maker/understander-or-things is enough without us getting cease & desist/DMCA/strike letters.

Is this an attempt to have them all shut down? The police don't care if you're an exit node or a child pornographer, if you start transmitting that stuff you're going to have a bad time.

Probably not realistic for most. Although a relay might be a better idea.
