It costs at least 5430 satoshis to create an output at the moment. Is the same spam limit applied if the script is OP_RETURN? If not, I would be concerned od opening a cheap spam.

OP_RETURN outputs are provably unspendable *and* not included in the UTXO set, so they're not dust (the client makes this check and handles TX_NULL_DATA outputs separately).
