That's an interesting thought. It does bear mentioning that
unaccelerated qemu performance isn't too good, so this would probably
not be the best choice for huge files. But it is an interesting
solution.
Yes, I will have to play with it and see how it performs. I don't
think I will be placing any large files in it, though, shall see. And
yes, idea is interesting, and I'm trying to think of drawbacks to it.
And, although I came up with it "unassisted", I must say that after I
thought of it and started googling, someone on slashdot mentioned it a
year ago ;)
On a less happy note, sorry for never replying to your query about
commercial systems. I was trying to formulate some reply, and then life
got in the way. I have some more time tonight, and all - but the answer
boils down to 'there are no cross-platform solutions I am aware of'.
No problem, I do that too often myself ;) And yeah, I'd be somewhat
surprised for someone to either offer commetcial tool to be compiled
by the user (though, VMWare somewhat does that on linux...), or a
binary for OpenBSD....
Also, have you considered something like CVS (Subversion, darcs, ...)?
It's very much possible this has already been mentioned, but Subversion
for instance, which is the one I am most familiar with, allows checking
out subtrees over SSH, for instance. Add secure deletion, and one is
most of the way there [1].
Well, yes, but I am more thinking of a "local" file storage - read:
"how to carry things on my laptop/pendrive that curious people won't
be able to access after I switch it off", or something to that effect.
But, that is an interesting option for the smaller files, in an
environment where you have network and are able to punch out into ssh.

[1] Not that secure deletion is really useful, unless you also take
great care that no editor or the like ever writes to /tmp, and so on.
Or wipe /tmp too ;)
