So what did they do in Chicago that prevented any other woman winning the race? Fact is Paula had everyone dropped with about 10 miles to go, it's not Ndereba's fault she couldn't keep up that day. If you are going to make that claim, then you have to say the same thing about 2001, when Ndereba had Rojo running ("guarding") with her until she got clear of the women's field.
The pacer thing would be a non-issue if races could build as deep of fields with women as they can with men. But the fact of the matter is there aren't enough women to do that yet -- although I think someday that will be the case. If somebody has the courage to see how high they can raise the bar, I don't see any problem with them getting help from the men because there aren't any women out there that can help by racing the distace. Until a few more women reach the point that they can run with PR, she will never actually "race" the distance -- it will always be a time trial. So if she wants to work off a bunch of 2:15-2:17 men, just like KK et al work off of 2:06-2:07 men, I say go right ahead.
I think instead of scrutinizing and complaining about Paula, we should take the chance to appreciate the fact that someone has a special talent and is taking her sport to the next level. Time might tell differently, but I what I see her doing to the sport is the exact same thing Jordan, Kobe, or Tiger Woods are doing to theirs, taking what we believe is possible to a whole new level. And if she needs special considerations to do that, then so be it.
