Well, something bout their homepage (Kaltura) dispises FireFox on my Ubuntu machine; so I'll have to wait to fiddle with their site till later in the afternoon...
If they allow embeddable tags however, it'd be simple to syndicate media from the script to the UBB... Now tying into the membership data however, since this is the first I've heard of Kaltura I'd have to say that I doubt anyone has a working integration drawn up to utilize that at this time.
