I just had a look at wcheck-mode and it looks very interesting.
Would you be interesting in contributing the code (we could at
a minimum include it in GNU ELPA, tho I think it might be worthwhile in
Emacs itself).

I see it is "display and timer driven".  The "display driven" part is
interesting since it saves you from having to "touch" text before it
gets syntax-checked.  And the "timer driven" part makes it less
intrusive performance-wise.  Also it operates on larger chunks of text
at a time, which is more efficient.

I have a question: why does it use window-scroll-functions and such
hooks instead of using jit-lock?  [ I've been meaning to try and
implement a new spell-checking package using jit-lock, but it seems
to keep getting lower on the todo list.  ]

One downside for the user is that ispell.el's M-TAB might not work as
well since by the time wcheck's timer runs to discover your typo, the
user might "too far".
