[fraanro <fraanro@arrakis.es>]

I have done tests with Video over IP, both Multicast and unicast on top 
of a L2 MPLS VPN Lasserre. Around 100 Mbps of IP Multicast and some 
unicast sessions (4 Mbps each) on a fully loaded network using 
Smartbits. With adequate priorization the image in the TV is just 
perfect.
