Running saned from xinetd (gentoo)

Trying to share a scanner with Sane. Got a Windows box to connect and
properly scan when running the server "standalone" (saned -d) as root
and as saned (changed the shell temporarily), everything works fine.
However, from xinetd, scanimage -L gets:
[net] connect_dev: trying to connect to 192.168.0.19
[net] connect_dev: [0] connection succeeded (IPv4)
[net] connect_dev: sanei_w_init
[net] connect_dev: net_init (user=manu, local version=1.0.3)
[net] connect_dev: argument marshalling error (Connection reset by peer)
[net] connect_dev: closing connection to 192.168.0.19
[net] sane_get_devices: ignoring failure to connect to 192.168.0.19

Here's my saned xinetd file:
service sane
{
   port        = 6566
   socket_type = stream
   protocol    = tcp
   wait        = no
   user        = saned
   group       = saned
   disabled    = no
   server      = /usr/sbin/saned
}

and the content of the messages in /var/log:
Dec 9 01:21:14 hades xinetd[6475]: START: sane pid=32319 from=<internal
ip>
Dec 9 01:21:14 hades xinetd[32319]: FAIL: sane address from=<internal
ip>

I hand-created a user saned and a group saned, and made sure that the
/dev/usb/scanner0 device belonged to the right group (although it was rw
by all). I've searched the net, but everything that's said, I've done,
and I can't figure out the rest :( (maybe it's just way past my
bedtime...)

Anyway, if anyone has ideas, I'm open :)

Thanks!
