Hello All,

I know it is not really slipstreaming but the end result is the same and slipstreaming just sounds cool.  So you can do this for both SharePoint 2007 and SharePoint 2010, and I would recommend that you make it a habit that as you introduce the update to Production you update your slipstreamed install.  Maybe even have it as a step in the change management.

Here is a TechNet article and a blog entry from a fellow PFE that should sum up everything you need to know about how to do this.
