If you mean the operating system might allow the security to be bypassed 
then it would indeed be a serious bug :-)  When accessing files by 
FileId on NTFS then the file's access control list is checked. In the 
pre-Darwin days I believe files on HFS+ were addressed by file IDs but 
I'm not familiar with that environment to know how the security worked. 
But perhaps you mean a security manager? In that case then a mapping to 
the name space would be desirable to make configuring the security 
policy usable and consistent.
