Besides broadcasts of course I couldn't find a scenario where say two switches had a FWD port on both ends that were NOT root directed and could send unicast ICMP's across. If this is the case, I missed it in my career/study in the past. A neat find but I also want to clear this up somewhere before I go assuming things.

Remember, there is only one root switch in the network, every other switch has only one root port (port leading to the root or upstream), all designated ports are leading away from the root (downstream). There cant be a situation where two connectet ports are designated/forwarding on both sides. One side must be root port or it will be blocking. EDIT: Think about it this way, in hypothetical situation where you would have two ports designated/forwarding on both sides, that would mean that both switches have already a root port (both of them have better path to reach the root), so by definition this hypothetical link would have to block on one side.

EC doesn't do that. EC sends a flow over a single member link via hashing a field in the header. PPP gives a number of advantages over HDLC. PPP has more protocol support (due to a protocol field in header), load balancing, authentication. The header and trailer of PPP and HDLC are very similar. PPP is pretty much HDLC 1.5. HDLC and PPP are both L2 protocols.
