NFSv4 and SELinux

Hi. I've just installed Fedora 9 today in order to test NFSv4 through SELinux. I know that sending context across the wire is still in progress, but could I find some patch to test? Is there anything I could test to make it work? I also would like to make the context mount option work with NFSv4. The mount command doesn't give any error at mounting but when I list the context of the NFSv4 mount point I get "system_u:object_r:nfs_t". Is there any way to set context for the mounted points? Any help would be appreciated.
