Of course, this will be one of the first uses.
I already have som ideas: There will be sort of a central "event 
scheduler", where drivers can deliver events (key presses, alarms from 
temp sensors or fan rpm measurements, timer events, ...) and one can 
register "handlers" which will be called for every event. There may be 
some sort of "event classes", where a handler can be registered to.

Providing a "scrolling" feature will be quite easy. There are already 
two framebuffers in every driver, one of the size of the display, the 
other of the size of the layout. So one just has to modify the offset 
where one framebuffer will be copied to the other one.

What I have to do for the nexcom box is to provide a capability to 
manually set up the IP address (along with netmask, gateway and other 
networking stuff) with the display and keypad only. This will be far 
more complicated. Honestly, I don't have any idea right now. Maybe there 
will be some special widgets for this?

Well, I even appreciate the sound of my vacuum cleaner :-)
