[ale] NAS in Linux/windows network

[Pete Hardie]

Due to impending disk failure on the wife's laptop, I'm considering
some form of external HD, so that she can keep her important files
somewhere that can be accessed from more than just one machine. 
Anyone have pointers to NAS or such? - I've got USB external drives as
a possibility, but they are not  accessible from 2+ machines at once,
and so I'm interested in some form of network drive

TIA,
