I've been running mine by-passed for 4 months, and right away it seemed I have better throttle responce. Cooler intake air.

As we get into fall weather, it feels like I have 20 more HPs in the early morning.

In the diagram, you bypass the existing lines (the ones with arrows) by using another hose which I have drawn in with a thick black line.

(I was going to do it in red, but it wouldn't let me and I didn't feel like screwing with the settings.)

Not so much emission control, as keeping the throttle warm so the condensation doesn't collect and freeze the throttle plate open.
It's happened.

Yep. I have never heard of it happening, but this is the correct explaination.

The new hose that you are implementing in that diagram, it's hard to tell, but is it right in between the intake manifold and engine? BTW, what type of hose do you all generally use when doing the mod?

i did this a few years ago, first with my N/A motor, then with my GTE. it's easy to do, and i just used some of the correct size hose from the parts store.

(i bypassed the ISC too)

If you bypass the ISC, won't you get a crappy idle? From what I understand the ISC measures the temperature of the coolant and adjusts the idle accordingly. When its cold the idle raises and lowers as the coolant warms up.
Or am I completely wrong at what the ISC does?

I think it runs through the isc for the same reason that it runs through the throttle body, to keep it from freezing up.

No, the ECU temp sensor off the thermostat housing measures the temperature, the ECU then opens or closes the ISC valve. I used to think the same thing actually.
