The only possible problem with that is if a client is unhappy about the 
error returned when trying to chmod.

It's on my to do list to add another mode (perhaps ignore) that behaves 
exactly the same as restricted except that it does not generate errors, 
it will nop the chmod and return success.

Is the Linux client explicitly calling chmod/setattr? There's an 
unrelated issue with NFS where a client using exclusive open will result 
in a broken ACL because of the way the mode bits are overloaded in the 
NFS protocol for that operation. It's fixed in NFS 4.1, but there's no 
4.1 support in illumos yet...
