Yes, this should probably be addressed.  And we should also investigate
this issue for other platforms, since they probably have different 
constraints.

I think it shares the same limitations.  From:

GetShortPathName Function
http://msdn2.microsoft.com/en-us/library/aa364989.aspx

lpszLongPath

    The path string. The function retrieves the short form of this path.

    In the ANSI version of this function, the name is limited to MAX_PATH 
    characters. To extend this limit to 32,767 wide characters, call the 
    Unicode version of the function and prepend "\\?\" to the path. For 
    more information, see Naming a File.
