Actually, I really just need something which can do both broadcast and multicast in a tunnel sans encryption.  The tunel really just exists to carry those items across mediums which may not support multicast/broadcasts without it being in a tunnel.
I am not sure, but with tunnels (CIPE or others), is there latency introducted by the tunnel?  It would seem, if a tunnel places multiple original packets in a tunnel packet, that there may be some artificial latency while a tunnel 'waits' for packets to fill a buffer.  If this is the case, then a solution which can configure this allowed latency would be great.  I saw GRE (well, saw the title and how expandable it was) but was looking at CIPE because I really don't need huge things from a tunnel.  Thanks for any info in advance!!
