I just noticed something - the SharePoint Central Administration site in Office 2007 is just another site collection. This means that you can create lists, subsites and even update the security settings. Heck - you can even modify the web parts on the OOB admin pages! Have a look at the Site Actions menu next time you drop by your Central Administration site.
This is a bit different to version 2 where Central Admin was a very customized site and there wasn't much you could do in the way of modifying it.
But with great power comes great responsibility. Now it means that you are going to have to consider what ways you will customize the Central Administration site for your web farm (of course you could just leave it as it is, but where is the fun in that?)
