Jamie,
I'm curious as to why the proponents of the "embed the url" want users to remember the url. I would have thought they'd want users to remember either the name of the site or what you represent.
To be honest, though, I wouldn't have a big issue with the suggestion but for one thing - what's suggested isn't memorable. It might have been okay if it was just /remembrance or /dor, but I don't think the two together are catchy.
Studies that support your case would be nice to have, but I don't believe there is a lot freely available.
