Even if the code is open source it can be made secure to my 
understanding. The MPEG data stream would be encrypted of course!

The server can interact with the client to use such a public key 
exchange protocol. With this software solution compared to already 
approved hardware solutions the clients can be easier exchanged or 
upgraded. Just the major studios have to approve that.

One would just need some kind of SIP protocol in front of VLS/VLC to do 
the authentification, format handling (if one needs that) and to start 
the RTP interaction on some UDP port. Or just on 1234 unicast or 
multicast as now.
