I will try to get time next week to reply to you on this. Part of the 
issue with your current approach is that it breaks PosixFileAttribtues. 
There are also issues trying to force the API to optionally support a 
subset of POSIX attributes on some zip entries and not on others. So 
several issues that will need consideration.
