Hopefully I am posting this silly question in the right place...

I was wondering about the possibility of using loopback files on a physical disk to create virtual disks that could shrink or grow as needed. Something like RAID 0, but instead of using block devices, just using files. If I need more space, I just add another loopback file to the pool. If I don't need it anymore, I just remove it. But doing either of these things doesn't damage the data. Does anyone know if this is possible?

Similarly, I was also wondering is it's possible to mount multiple NFS or Samba shares to one location and have them all appear as a single "mounted device". For instance, if I want to mount th C$ share on an NT box and 10.0.1.1:/home on /mnt/files. Is there a way to do this?

Thanks.
