DBC vs DBW
I vote for electronic throttle, as it eliminates the IAC mechanism which is a royal pain. Also, if you're doing bracket racing it's easy to limit power by opening to 90% instead of 100%.
I'm pretty sure there is a table that regulates the input lag, you can tune it to whatever you want.

I like the cable and your best bet there, is a van PCM
which will give you that plus 4L80E if you get one from
the HD series. But you may not have as many custom-
OS options since most vans aren't hopped up like that.
On the flip side, a wire throttle always brings you a lot
of traction control options (you might need some) that
can help you out if you are inclined to work with them
rather than dummy them out (some folks want to put
on a smoke show, some want to shut up and go). But
a nuisance until you get them right. Also can help you
add months between transmission rebuilds.

There are 3 table that control the acceleration rate, but none that I can find that could control the actual response throttle lag. I fon't see the IAC as being as much trouble or failure prone, as the motor controlling the throttle. The throttle motor is constrantly having to adjust a larger and more exposed mechanism, where the IAC only hase to operate during PCM controlled idle functions. I'd agree with your Bracket Racing statement, in fact you could control more then max throttle, properly done, you could control acceleration rates through out the gear ranges. Personally I go for drive by cable, at least until somebody start producing easy to fit compact DBW petal assemblies
You maybe limited to 3 table by the tuning software.
I have monitored several factory tunes that go WOT (TPS) with less than 25% APP when accelerating from a dead stop. The same car will not go WOT (TPS) when the APP is 100% at highway speeds
