I submitted the following as a blog post for here on WP Tavern. However it seems there is a better product in development anyway so there isn't much point in writing a blog post about this when something better will be along shortly anyway. Since I created it I figured I'd post it here for you guys to try out if you have a use for it though. It could definitely be made better, but it sounds like someone else is onto that already anyway.
There's more information about it on my blog too:
A tweet by Jeff Chandler mentioned how the "WordPress five minute installation". However I've often found it takes me a lot longer than five minutes due to thelaborious task of uploading stacks of files via FTP. My broadband connection is capped at 128 kB/s upload which can make uploading all of the WordPress files quite a time consuming task.
To speed the upload process up I wrote a very simple script which allows me to upload the raw wordpress.zip file as downloaded from <a href="http://wordpress.org/">WordPress.org</a> and when I run my script it automatically unzips it. The raw zip file is significantly faster to upload than all of the files on their own. In case the tools is of any use to the wider WordPress community, I've made it look a little prettier and have posted it for download.
