nfsv4?

[Karl Dall]

Hi,
i only found this 5 Year old Message > 
http://lists.busybox.net/pipermail/busybox/2006-July/057463.html.
I am using a Settopbox with Busybox Version 1.18.5 and it seems that 
nfsv4 is still not supportet, or am i wrong?
i only get back:
root at et9k:~# mount -t nfs4 192.168.0.5:/movie_archive /media/nfsv4
mount.nfs4: No such device

Are there plans to add NFS Version 4 in future?
Appart from this, thanks for your great Work!
