re: Its going to need to have a proper interface for talking to the bluetooth phones.
I dont think you will find a "--museum-mode+bluetoothsend" specially designed into most software.
actually: the sketch feature preloaded on each Internet tablet has a blue tooth send option...

re: As for sketching, liqbase does a good job at covering the OS and being a fullscreen application in active development could be tailored to your needs.
actually: i'll google liqbase and find out what it is

re:Images can be saved as png at present, not sure about a bluetooth interface, but you will tell me how important that is, have you considered simply uploading sketches at the end of a day or as required to a webserver?
actually:from my research png is the best file format, it works on the most phones. People will be drawing, saving and then instantly blue tooth the pictures to their mobile.


re:might be more flexible and would allow the smaller phone free visitors to use the device.
actually: everyone has a phone, and i want to see if groups of school kids are queuing up to use it or

not? other project at a later stage.

re:The last I heard about you was you were doing software updates of things and wanting to do things automatically via a cron job, did you manage that?
actually:i do many things so many things i can't remember what a corn job is, but recently i failed to even install the debian chroot. usually i can work out why i fail but that time i could not.
