Mark,
I'd avoid Menu Links if you can.
What I do for things like that is put a container directly below the menu in the template, and use a structure, based on folder, to pull these links. You could just add them to the nav pull as well.
Typically, this is for 'external' links and/or intra-site links, so I can a) track them, and b)style them differently. And, of course, import/export as a structure.
I think it is poor usability to have items on the 'menu' that take you off the site/folder. Links that navigate you away from the menu you are on should be clearly marked/identified.
They are much easier to maintain this way, particularly if you have the same sort of links in many folders (i.e. many of our departments might link to 'Admissions').
The way menu links currently operate, you'd have to visit each folder and update each instance - that sucks.
Alternatively, you can also set up blank 'pages' with redirects on them (in the advanced menu on page properties, you can point it somewhere) which can be used instead of menu links and these are also exportable.
This also allows for easier future building, as the page is already there you can just add content and remove the redirect. If you go this route, pick a dummy template or something so that when editors get to the page they realize it is forwarding, you cannot tell otherwise except on live.
