As many of you may know, I run my small web hosting company, and lately, a lot of my clients have been using WP blogs. Like myself =). What I am working on right now, is a WP Upgrade / Install script. I would put in the variables, such as where the script is, and such, and it will upgrade / install the WP blog there. It is going to be somewhat a server script that in reality, would upgrade WP when it is out dated. I might plan on selling it commercially and get some profit off that shiznawt.
I plan to widen the support to forum systems, and other scripts that the average web host would need. It should be very very interesting to see how well it works. I just finished the installer part. It is still mostly chicken scratch around, but it is simple and it will install the WP blog and return the admin/random password string that is genearted by WP on the installation page.
It is pretty sick, and I already have some people who are interested in purchasing it.
