I previously mentioned on my personal blog an effort around SharePoint global deployment recommendations. Working with the TechNet SharePoint UA team, Brenda Carter, myself and many from the Ranger team including Steve Peshka, Dino Data-on, Kimmo Forss, and Luca Bandelli, we have just published the guidance. This guidance includes recommendations for three different deployment configurations. I highly recommend reading through this guidance if you are planning or have deployed your WSS or MOSS farms globally.
