Interoperability is generally poor in this area so it's probably not 
worth spending too much time on this. One exception, if you have the 
cycles, is to test with the Solaris CIFS service. It provides very good 
interoperability with Windows environments so if you have clients 
accessing named streams on CIFS shares then they are accessed as Solaris 
extended attributes.

Linux implements ACLs based on the withdrawn POSIX 1003.1e draft 17. 
There is a patch, maintained by Andreas Grünbacher from SUSE, that 
implements NFSv4 ACLs on the ext3 file system. I haven't had time to 
play with it but in theory we should be able to get this to work.
