Here's a good question for most people here... Instead of worring about hosting on a dedicated server, why not focus on building a strong Peer-to-peer network with AMVs?
Example: I use WinMX and share all MP3s and Videos that I download, from both here and other places. People are always downloading from me, plus they are downloading other parts of the same file from other people. This leads to faster downloads and happier people! (because they can get their anime fix faster)
Why not start a standard here on a-m-v.org where we post an indirect link to http://www.winmx.com/ and in the Comments, put WinMX: Creator - Title [a-m-v.org].avi or whatever extention it is so that people know what to search for?
Running a dedicated FTP server can be really bandwidth intensive, but the more people that have dedicated internet connections that share the same files the faster the downloads are and more reliable. FTP servers aren't very reliable and you frequently have to "get lucky" to get connected, where WinMX has queueing available...
Just food for thought!
