Yes, that seems to be one of the better "workarounds".

No, from what I tried out, Linux is unable to mount files at all. Maybe
it's because of the implementation of the loop option of mount, maybe
only nobody stumbled over this feature in Solaris and found it usefull
enough to implement in Linux. With Linux you can only mount directories.

I know, but another (even it it's used) box is not yet an option.
