. The question is then what behavior should be assigned to
a large tablet without an embedded screen. It should have POINTER set
for sure, but should it also have DIRECT set?

Any large tablet without an embedded screen can be used in the 2 different ways:
1. The projection on top of it so it becomes a direct device.
(this case is also used when you project 3d 120hz on top of multitouch
devices: iMuts)

2. Simple indirect device, even if it's large:

Two-finger scroll is actually used in a direct manner in that
video. (Which, btw, does display some fresh concepts. :-))

I think the bottom line is that even if the "directness" of a device
is configurable, it still needs to have a default. Moreover, the
notion of kernel mode settings could be applicable here too.
