Using scanners on terminals (Sorry if duplicated on list)

I am using PXES9 now in our school labs, and it runs great! Last year
the machines ran as fat clients, with a scanner in each classroom for
the students to use, and I would like to get them working again.  I have
a few questions...

Information on the setup: 4 different labs booting PXES to connect to a
Windows 2003 TS.

Has anyone set up scanners to work on these terminals? Does anyone have
a how-to in the works?

Would the scanners be available to Windows programs to use, or would it
have to be used in linux?

I would like to be able to use network scanning to scan from any
machine, would I need a dedicated machine to share the scanner?

If I can get this working, I will more than gladly write up a detailed
how-to for everyone else.
Thanks,
Bruce
