I am not sure how long this has been offered, but I just noticed yesterday ...
Trocamania moved their server and updated their site and are now offering Marriott rewards points for redemption of TROCAS.
If you haven't signed up yet, this is just one more reason to do so. They are offered in 1000, 1500, 2000, 2500 and 5000 point increments.
