The kaltura plugin has to be one of the best add-ons for buddypress, i am verry impressed with its list of features.
We have released an updated version of BuddyPress media plugin here - http://rtcamp.com/buddypress-media/
New version is developed in a way so that it does not have any dependency on Kaltura. But for people who like Kaltura, there will be an option to use Kaltura.
Kaltura option will be available next month.
