I use Gentoo and they don't have a saned initscript in /etc/init.d for

How about /etc/sane.d/epkowa.conf and /etc/sane.d/epson2.conf?

Is iscan-network-nt available for free? I had assumed
iscan-network-nt was included in Gentoo's iscan package but I must
have been wrong. Does anbody here know if there is an ebuild
available? If not, I'll file a bug with Gentoo.

Could the epson2 backend work via "net" even though the Artisan 710 is
listed as unsupported on the SANE website?
