I found out it is possible using cifs.
install kmod-fs-cifs & cifsmount
do insmod cifs
then mount.cifs //networkshare/shape /mnt/share
There is a bug in kamikaze however that prevents this.
cant do (insmod cifs)
I installed backfire and got it to work however there then just isnt enough space for mpd so i need a minimal build of backfire with out the web interface and stuff. My problem now is that you need a linux machine to do this so i'm hoping someone can build a minimal brcm 2.4 backfire image for me.
I'm not sure exactly how the cpu will handle it but i'm assuming if it can stream off the net it will be fine over the network.
If you have a linux machine please will you make an image for me.
