Running a FTP server on the host with proper permissions is sufficient for 
this. There is plenty of FTP servers available for all platforms where 
qemu runs.

I don't quite get why everyone insists that qemu should have various 
network services built-in. There already is too much of that imho (TFTP 
and some SMB glue). The goal of qemu is to emulate the CPU and required 
hardware, not to provide full network server services.

wrt r/w access it should be pretty trivial to extend the tftp server to 
allow write access.

btw: The SMB server (Samba) provides read/write access if you insist on 
it. All you in theory need to do is to set up the password file on the 
host.

What would perhaps make sense in this discussion is to generalize the 
user-net port redirection used for the SMB access allowing it to be used 
in a more general manner, then perhaps even ripping out the smb (Samba) 
support glue and replacing it by a wrapper setting things up as suitable 
using the general slirp pipe support. So instead of having the smb support 
glue hardcoded within the qemu binary just have it start the suitable 
daemon wrapper when the port in question is accessed. Apart for allowing 
it to be used for other services than SMB it would also allow the SMB 
support to be tailored more closely to your needs.
