Under Linux it is now possible to emulate the BeOS attribute support via

xattrs. It can be enabled with the configure switch "--use-xattr". Note
that the amount of data stored in attributes may be limited by the used
file system -- e.g. AFAIK ext3 has a limit of one block (usually 4 KB)
for all attributes of a file, which might not suffice. XFS should be
fine, as should ReiserFS 3.6 (or any FS which stores attributes in
hidden files).
