Next to impossible to do portably. I am not sure how user-net port redirection
even enters the picture - once the FTP daemon is set up, the guest sees
the FTP server on the host (admittedly on a nonstandard port, but is that
such a big deal?).
I agree that this is a better option than shoving all that FTP server code
into qemu, but I think that this is still overkill.

Can you explain what you mean here?
<list of protocols to be used via user-net deleted>
Making any of these builtin is overkill considering what we already have.
Setting these up externally is less overkill, but still...

I meant using native Windows SMB functionablity, not Samba ... but someone
else replied saying that would only work if given administrator access,
which makes it a moot point.
So this is not a portable solution. Samba may not be the best solution anyways,
since it provides a Windows-specific network filesystem...though Samba 3
provides Unix extensions.

Right, I'm looking into doing that right now.
