Shouldn't be bad at all.
Have a look at the autoscroll code. It's already doing some fairly simple
work to try to intelligently keep the cursor on-screen. Methinks the
algorithm could definitely be improved, and adding a fatter cushion is an
obvious tweak.
The only thing to watch out for are the usual overconstraint screw cases of
content too big for its viewport (narrow and short windows, big fonts, etc.)
so that the display doesn't jump around too much while typing.
Have fun tweaking!

PS: Does this really need to be a preference, or could we come up with a
better default, say .5in or 1/8 visible screen real estate or something?
