since I am almost out of battery I won't comment long, but the place for comment is highly theoretical. the transaction with comment is legal according to protocol, but non-standard and as such the official client refuses to propagate it through the p2p network. and because there is a client monoculture, you are out of luck with non-standard transactions if you are not owning a mining pool yourself. IF the non-standard transaction gets into blockchain, THEN the comment stays there forever. but it really never propagates.
