Thanks for your reply,

I haven't heard about MSEC. I've been searching for it and all i've 
found are RFC's of 2004, 2003...I think this standar has been 
discontinued, and there isn't any implementation.

About the tunnels i've had problems with multicasting packets over 
tunneling. Firewalls and packet organizers don't like tunnels...so this 
solution is not valid for me. I need a solution that works in many 
environments, not only with tunneling.

I've been thinking about Pluto. Can i use the keys obtained by a unicast 
connection made by pluto with any other program? That is, I make the IKE 
with Pluto unicast with a Key server that gives me some keys, and i read 
that key from other program to decode the multicast flow. Is this 
possible? Could i modify the pluto code to get this?

Thank you for your help
