I dont think people here, however well intentioned could keep a swarm well seeded beyond a few weeks.
Note that was 25 GB in about 12 hours, not bad compared to a fast BT swarm (+ we are currently at about 45 GB).
I specifically discounted BT because the swarm would be too small to maintain. These files will be on the server 90 days after the last person had downloaded them and turned off their pc (and I think I can renew that via the web management tool).
