Paul,
My reply to you bounced. I know you must read this mailing list, so I took
the liberty to post it here. If you were asking yourself why nobody ever
answers you, this is the reason why :-)

I don't think it's a foolish road to go down to. I think it's just one of
the
paths leading to full emulation (if that's at all possible). It's more
difficult for the emulator to be able to emulate devices and filesystems
than
it is to port a tool in such a way that its functionality is emulated. In
any
case it *is* emulation, only on different levels.
