wordpress mu as a intranet portal « WordPress MU Forums

I am looking to setup wordpress mu as our corporate intranet portal.
the plan is to setup one main site as the portal and then additional sites for each division to use as a basic website to post documents and such.
wordpress mu 3.0 seem to fit the bill but would like everyones opinion on this

Has anyone setup a wordpress in this fashion? if so i would real like to chat with you

Also i welcome any suggestions.
