Over at Archive.org, you can actually just upload everything in one huge file and they'll host it all in various formats(torrent, zip, rar, etc). That "Sketch the Cow" guy did it a while back with a bunch of mags he had uploaded. He uploaded them all individually, but then also did one huge 23gb upload that included all of them at once. I'm not sure what their size limit would be, but even if you had to break it up into chunks, it'd definitely be easier than doing it one by one. I notice a lot of people asking the question of size limit, and though various answers are given, if you tell them what you're trying to upload and its size, it seems like they'll give you an email address to contact them directly so they can help you do it.
