Darwin doesn't have NFSv4 support unless you trust an ad-hoc piece of 
software with no support. I remember seeing a comment about Solaris 
needing patches or an upgrade to 10. Linux has had support in kernel for 
a little while now though it may not be there by default on many 
distros. Of course, openafs also needs to be "enabled" on many distros 
as well.
