Maybe ;-)

If you can get your modem to run saned, then yes and yes.  The imagescan
"package" includes a SANE backend.  It works with any SANE compliant
frontend including saned AFAIK.

If you run saned on your desktop or your modem, the rest of your home
network can access that in order to scan.  On your desktop (or modem)
you would only need support for the USB-based protocol.  This does not
require any of the non-free components "polluting" the imagescan
"package".

If you don't mind using the non-free network plugin for imagescan, there
is no need for Windows.  Using the SANE escl backend or sane-airscan
does not require any Windows either and should support access via a WiFi
connection AFAIK.

Hope this helps,
