Aside from having to specify whether or not the symbolic link points to a file or directory, what are the limitations of symlinks? I'm a bit curious, having used them myself but never encountering any significant issues with them. I remember hearing at one point that Windows Vista could only create up to 31 links inside a directory, but I just checked on my Windows 7 machine and was able to generate over 600 links to a directory without a problem, so I'm guessing Windows 7 worked around this issue.
