How can I filter out files in root directory like the Finder does?

My app has an NSBroswer view that the user can files and folders in 
and I need to filter out all of the stuff that they shouldn't normally 
see, like the Finder does.

Following previous postings on this subject I've implemented the 
following:

  - Read the .hidden file from / and filter out anything listed in 
there (does not appear to be used in Leopard)
  - Call LSCopyItemInfoForRef and test for kLSItemInfoIsInvisible
  - Call FSGetCatalogInfo(kFSCatInfoFinderInfo) and test for fInfo-
>finderFlags & kIsInvisible


That gets almost everything except /home and /net, which the Finder 
does not show. I thought there might be some sort of xattrs on those 
directories that would help, but there aren't any xattrs on them.

Are there other tests I'm missing?

Thanks,
Dave
