I was thinking more of the ability to use existing windows twain data sources
with Linux SANE applications - if this could be achieved then nobody will
need to write Linux specific data sources, although using proper SANE data
sources would still be preferable for some scanners.
Some SCSI scanners can already be used under WINE running windows twain
applications using an emulated ASPI layer and Printer port scanners work by
allowing SANE to allow windows apps to directly access printer port - if this
can be made to work for USB as well and a SANE wrapper could be written to
appear to the Linux Frontend as a normal SANE device and to the Windows Twain
driver as a Standard Windows Twain application then the only difference to
the user between a true SANE backend and a windows Driver using the SANE
wrapper would be having 2 dialogs displayed (the SANE scan dialog and the
TWAIN scan dialog) but many windows twain drivers can have their scan dialog
bypassed.
I hope this clarifies the situation,
Nigel
