I'm running xsane .89.  And this is my output from 'rpm -qa |grep sane'
sane-backends-1.0.8-5
sane-frontends-1.0.8-4
sane-backends-devel-1.0.8-5
xsane-0.89-1

It is the same on both PCs.

Yes, when I run scanimage -L as a normal user I get:
device `epson:/dev/usb/scanner0' is a Epson Perfection610 flatbed scanner

I don't have a user named saned.  So I should create one, then make that user 
own the saned executeable, then make sure xinetd is going to run saned as 
that user?

This works.  I get:
device `epson:/dev/usb/scanner0' is a Epson Perfection610 flatbed scanner
device `net:localhost:epson:/dev/usb/scanner0' is a Epson Perfection610 
flatbed scanner

This works fine.  I end up with a scanned image.

If you mean 'saned -d', I get this when I run that:
[saned] main: starting debug mode (level 2)
[saned] main: bind failed: Address already in use

And when I run 'saned' it just sits there waiting for me to do something 
somehow until I hit Ctrl+C.

Thanks for your help.
