Here is a handy reference for keeping this all straight:

<http://www.comentum.com/File-Systems-HFS-FAT-UFS.html>

In my personal experience with OS 10, I have found that the Finder
usually keeps things straight for files or folders containing a
slash(/); but often times applications do not. Overall, I found it
easier to avoid problems by not using a slash in a folder or file name
in 10 though I often did in 9 and previous. (RIP, A/V ƒ)

I still don't even put spaces in filenames that might leave our Macs.
Our sever is BSD, most of our clients use Windows (some Mac); we use
underscores instead of spaces, only one extension (and one that makes
sense), and no punctuation (no kangaroos and one redeemer).

Methinks that might be problematic if you are dealing with multiple time
zones, but then you are probably getting into application or business
specific areas.

I don't think NTFS has had any significant changes since NT 4.0, so
don't expect Vista or Windows 7 to be any different here.
