My car is making a high pitch screeching noise (occasionally) when driving along the road at about 25mph in a straight line. This occurs when I am not applying the brakes. I cannot tell if it is coming from the front or rear wheels but I have the EX so it has disc brakes on both axles. I am aware of some early cracks in the CV boots but I don't think they are busted open. Any idea what this might be?

Ripped CV joint boots are unlikely to cause this noise, a bad cv joint would make a rattling, click click sound increasing with velocity of a tight turn. I suspect the noise is either a loose fan belt or even a distributor that is seizing (which I have seen on the Accord at higher mileage) if it is engine related. If the noise is coming from the wheel area each brake pad had a metal finger on it that when it contacts the brake disc makes a high pitched noise. Initially it is more noticeable as the brakes are applied or sometimes when backing up but after a while the noise will be apparent even if the brakes are not applied.

Yes, I am pretty sure it is not a fan belt. I think you're right that I did hear it when backing up the other day and now I hear it when in motion forward. So is the metal finger the wear sensor for one my brake pads? I looked at them when we did an oil change (About 2500 miles ago) and they appeared to have plenty of pad left.
