I guess multiple initial seeders (cable ,dsl, fios, t1, t3, whatever) and lots of snail mail trades are the answer. High Definition's quality is worth the space, discs, and bandwidth in my opinion, especially something transferred from 35mm or 70mm film > 1080p or an HDTV broadcast captured at 1080p or 1080i, or an audience shot high def camera at 1080i (tripod, DAUD synch of course). If my ISP limited me to only a couple high def concert video downloads/uploads a month, it would still be worth it. So what if it takes weeks to download and then upload the same amount, it's high def!
