SMS on DMZ servers

Anyone have any experience with installing SMS clients on DMZ servers,
pointing them to a site that is not in the DMZ. These boxes are also
not in our AD forest, making the issue even more complicated. IF there
is a white paper someone can point me to, would greatly appreciate it.
I know this much, we will need to do manual installs since we won't
have exposure to a local admin account on the boxes to drop ccrs. Also
know we'll need to publish in WINS, since these boxes will not have
exposure to the AD schema. Anything else I am missing? I'm sure
there's atleast a few more things. Thanks!
