Any good Guides on using Wordpress Multisite for autoblogging

Ive got over 100 WordPress sites most of them hybrid autoblogs and need some way of managing them all efficiently in terms of upgrading, plugins etc.

I cant remember where I read it but it seems that the new wordpress multisite can be used for this.

Can someone point me to a good guide on using the wordpress multisite model for running my autoblog network.
