I am currently in the process of creating my own admin back end. I wanted to, when WordPress releases it's update and you get the notification to update your WordPress to the new one, is there a specific download location it points to? What I am trying to achieve is this:
-The customer gets the message to update their system
-when they click on update, instead of the default location of where the files are, a hack to change the location so that they are pulling in from my server. What I would do is host the new version of WordPress on my server as it comes out.
A secondary question to this:
-If there is a way to hack the location and set it to your own server to be able to download the new WordPress versions as they are released, I would also like to know if there is a way that, along with the WordPress udpates, I can send my own updates as well to my customized admin theme or my front end theme if there are any updates.
