When originally looking at kid seats, my wife pointed out the concept of a front-mounted seat, but with only one kid it seemed far simpler and safer (and a good bit cheaper IIRC) to use a normal rear-mount seat. I had to make some brackets to really mount the thing conveniently, but for my purposes it works very well.
Now with a second kid on the way, I'm contemplating how I'll go about carrying two kids on my bike should I want to take the new kid along before my first kid is really big enough to ride separately. Not that I ever ride very much or very far, but the front-mount kid seats I've seen online all mount behind the handlebar, which looks to me like it'd make a bike completely inoperable. Seems far more logical (and safer) to me to have something that would mount to the stock mounting points just like a normal cargo rack! Does someone produce one like that, or would I have to try making one myself?
