During Tech Ed 2007 in Orlando, I was able to grab some time from Kristian Andaker who is a Group Program Manager with the Exchange team for a quick video interview.  Kristian shares some information regarding OWA features / enhancements in the upcoming Exchange Server 2007 SP1. 

You can find this video on the Exchange Team Blog: http://msexchangeteam.com/archive/2007/07/17/446358.aspx.
