Something to watch: EasyWP is a one-file script that downloads and unzips latest WordPress build on your web server (so the average Joe doesn't have to download the archive, unzip on his computer, and then upload everything). The file is rather immature at the moment (using only fopen(), needing Zip PHP extension, these things) but will evolve. Eventually this kind of feature has to be integrated to WordPress, I'd say.
