[sane-devel] HAL and scanners.

[Étienne Bersac]

Hi,

First of all, i have to apologize for being away from computer since few
days. This was easter days. Happy easter days :D

About proprietary backends. They have to support SANE, but SANE has not
to support those backends. Actually, as Allan said, nothing will be
break. And it's up to the proprietary backend to provide its own HAL
callout.

The discussion is not about patching e.g. XSane to use HAL, but rather
to allow parallel unified device naming in SANE backends. This will
allow a HAL callout to compute mostly working SANE device name in order
HAL addon to open a device on plug and monitor its sensors, and much
more.

Regards,
Étienne.
