I've got the exact same problem in my '04 accord, 94k miles. Starts shaking at 60, stops at about 70, but only when I press the accelerator, and it shakes harder the more I press it.
The problem was first diagnosed by Tire Kingdom as a bent drive axle; fortunately I didn't get it fixed right there. I just yesterday took it to a Honda service center and they determined the drive axle is fine but something in the transmission is causing the problem. I don't know if it is a repairable problem, or even if it serious or just an annoyance. Since I'm selling the car in a few months, I'm going to leave it alone.
Just to be clear though, the problem is most definitely *not* alignment or wheel balance, nor is it the CV joint.
