Well, don't believe everything you read here (including this :-).
SendInput works fine with DirectInput on 2k and XP.
Of course, it may be possible to create a situation where it doesn't
work, like some app opening a *specific* keyboard instead of the
meta-keyboard GUID_SysKeyboard (I haven't verified this scenario). But
even with a filter, you're going to have that problem, because you can't
send your keys to *all* keyboards with a filter, just to one particular
one (otherwise you'd end up with duplicate key presses, which you
probably don't want).
