When you say "hash collision" are you talking about
http://crosbug.com/3225? Maybe that behavior is acceptable for
small-scale private use, but for large scale public repositories I'd
say it's totally unacceptable. Eventually, I'd like to see gentoo
officially distributing binary packages, so that we'll be able to
get a slice of the binary distribution pie. When that happens, we're
certainly not going to want to have race conditions like these in
our public binhosts.
