ATV2 with nfs through xbmc?

Has anyone successfully accessed an nfs share through xbmc on their atv2? I have my computer at home with a store of about 250gb of music which I want to access however going through samba just causes the atv to crash - I can access it but when I try to browse the folders it just goes extremely slowly, playback is very slow and then hangs.

I am using linux on the desktop PC and have set everything up ok however xbmc still cannot see it - I tried mounting the drive manually through ssh but it seems that the atv doesn’t support it from the command line so I am wondering if it is supported at all?
