I intend to put some effort in gphoto2 and see if I can make it part of my robotized observatory. Hooking a DSLR through a notebook is ok, but is way bulky and limited power and performance-wise. Ideally, the plan is to have the N810 connected to the DSLR on one side, and through wifi to my access point on the other side, through which then I can ssh/gphoto2/control from my desktop... I'll post some feedback if there is something that relates to this thread (=if I don't end up rolling my own version).
