Philippe you didn't understand... the Sha1 is normal at 32 digits but once it is computed we cut it to the first 6 digits to requery using less bandwidth. Yes there are more chances of collision, but the search result contains the 32 digits sha1 that the downloader can compare to the complete sha1 of the file he is downloading, so no downloads of collisions, only possible in search results. But in the end users get more chances to complete rare files and the network isn't under pressure as it would be with the complete sha1 requiery.
Do I have to understand that you are more for the kamdelia approach?? I'm feeling too that it is a less quick and dirty way to deal with requieries...
