Ok so from what I've read so far... 1. Looks like we should use the native power of Bit Torrent to do the bundling whenever possible 2. We should distribute over Bit Torrent and P2Pnext, but also have some way to see the footage ahead of time. Oh quick note about footage, this whole project is about trying new things and seeing what could work in the future. So don't expect us to be distributing RAW DV or anything silly like that. :)

I don't want to get into a discussion about the footage per-se because that's not the important thing. So to answer the points about the packaging. I didn't know Tar was just a way to pack together files with no compression. Now tar.gz makes sense to me :) It would only be worth using gzip (or any form of lossless compression) if the original data is of the type that can take it. It is also worth pointing out that is you "pointlessly" use a compression like gzip on a very large file where there is no usable compression that you simply slow down the process of getting to the data as you have to run the whole thing though unzip which at the very least needs 2 x the disk space. I am very much against using the tape-archive format for files in torrents. Most BitTorreent clients allow you to select and prioritise on a file-by-file basis using the format based on th .torrent file "filesystem header". If you have just one .tar file, you can't select which bit to download, your only option it to get the lot and then throw away what you don't want. If you want to use lossless data compression, the best place to use it would be in the BitTorrent client when they do piece exchange? The reason why we would like to Tar the files together is because of things like subtitles, artwork, cuts of music, other metadata pieces, etc. We're not just talking a collection of video files. I guess we're also thinking about the 5% of the audience who would actually do a remix with the raw project files. This would be on going rather that a one off, so we need the ability to handle everything from low rez 3gp files to ultra high rez animations at stupid frame rates What is wrong with a file system structure? What is the point of using a foreign (Unix tape archive) system?
