Also MtGox could take a position on my UDP streams idea, which could be any of the following without commitment:

a) Great idea, we haven't thought of it, and you're right, it would totally get information out immune to DDoS, we'll consider it but like anything else will take time
b) Great idea, but we don't agree it would work as well as you think it will, or for (specific technical reason) won't work on our platform
c) We haven't got a clue as to what this means
d) I don't have a clue what this means because I'm not a developer or tech guy myself, but I have relayed your suggestion to someone more technical, and he says (response).  (Hopefully this suggestion is more valuable than to merely forward it blindly like the latest facebook meme, since MtGox's reputation is suffering and this will actually solve the claimed issue at hand)

Just to be clear, using UDP to broadcast ticker data would be, for all intents and purposes, IMMUNE from DDoS attacks, because such a stream consists solely of outbound traffic which is not influenced by inbound traffic.  Unlike a normal stream, there is no inbound overhead for packets to acknowledge or to keep the connection in sync, packets which can be drowned out in a DDoS attack.  UDP is much more like a point-to-point radio broadcast: the signal gets sent from point A to B even if nobody's listening
