I agree with you but I was so fed up of installation because I tried it on other Hosts and the installation went wrong every time, so i was happy to find something like this.
for the record there is no such thing as unlimited webspace or bandwidth, and any auto-install programs actually suck, you learn so much more by downloading it, extracting it, FTP'ing it back to the server and running a manual install. auto install programs never take into account software requirements and have seen many broken installs in the past because auto-installers skip parts of the install.
If you want a decent oxwall install (1) get some decent paid hosting, ideally your looking at a small VPS @ around $30/month (mine currently cost $89/month) (2) install it manually so if anything goes wrong you know where it went wrong
