+## Goals
+
+* Monitor buttons 
+* Share devices 
+These feature imply that the software own the device handle, this is why the software expose acquisition API.

+* Acquire image 
+
+## Achievement
+
+This can be done through a dbus system wide daemon.

+
+## DBus API
+

+* [[GetImage|GetImage]] (job) 
+/!\ How to monitor ? How to get buttons events ? How should the image be transferred back to the client? 
+
+* A file descriptor or device node might be one way for transferring the image quickly (sending it directly over D-BUS definitely wouldn't work). 
+Signals : 
+
+* device-plugged (device) 
+* device-unplugged 
+* button-pressed (device, button) 
+* job-done (job) 
+
+## Scanner access
+
+Scanner access is done through the famous SANE library. Hope that HAL & SANE will work better together in the future in order to get devices from HAL. 
+
+
+## Sharing
+
+SANE has a net scanning protocol. However, it shows some limitation (basically, it's too slow for huge image). What to do ? 
+
+* It would be nice to come up with a new protocol for this like the D-BUS one, maybe with some kind of compression, like bzip2.  I wouldn't worry about breaking compatibility. -- [[DonaldStraney|DonaldStraney]]
