Enterprise twitter with Yammer

I just checked out the presentation by Yammer at TechCrunch50 and love the new twitter based enterprise tool they have built. Similar to when Facebook first started by only allowing education email addresses access Yammer works in a similar fashion by only allowing people that share the same company email address such as @yourcompany.com to view tweets from the same group.
