OK. I misunderstood how this worked. Because the relay agent mucks with the giaddr field, I had never understood that the relay agent is in fact sourcing a packet with its own source address (which contains the same info as the giaddr field). I guess back then, getting the source address of a packet out of the API was deemed to hard or something? So yes, I agree IPsec could be used to secure the relay-agent - server path.
