Looking at 2.4.1 there is a virtual memory filesystem, it used to be called shm fs, i didnt realise what it really was till now. On machines that dont have a lot of ram this would be ideal to use, previously i was thinking of trying to do complex stuff with loopfs... So we can use ramfs, if there isnt enough we can make some swap space (swap file would be easier than a swap partition) and use the virtual memory filesystem. Glenn
