Dear Remi, 

Thank you for the reply.  And if were here, you could 
see my big smile while reading your mail.  THIS is 
exactly what I, along with my other partner, had 
discussed last night.  :)  Unicast Authentication, 
Encrypt - Decrypt, chances of simultaneous use etc.  
I feel really great of myself that I've started 
thinking like you fine ppl do.  :)  

I'll definitely let you know if we can come up with 
something.  Actually, I was looking for if VLC-stream,

a.k.a. VLS, has already done this kind things.  
Basically we are planning for a CAS at VLS-end and 
one Authenticator + some other things upon 

And you are quite right.  You have got my view 
perfectly.  Any comments from Remi or anyone else
will be a big help for us.  If any other developer 
working on this issue, I like to discuss things.  

Thank you.  This list is really helpful.
