A:
. Scanners are usually tied to a single system via USB, not used on a network, if that's what you are crossing your fingers for. You can install on Windows OR Apples OS X, but the manual warns:
"Epson Scan does not support the UNIX File System (UFS) for Mac OS X. You must install Epson Scan on a disk or in a partition that does not use UFS."
At best, I think you have an either/or situation here - no sharing control.
