What
pitfalls will a DAR place in front of me if I fly a homebuilt here and ask
him to register it and give it an N number.

The major pitfall is that a DAR does not register aircraft nor issue N numbers.
You need to do this seperately (and before the DAR comes).

The real question is will he give you the experimental
airworthiness certificate.

As for that, I expect it is the same for trying to bring any aircraft you didn't build
yourself through certification. First you have to convince him that it meets the
requirements for the experimental--amateur built certificate: that it is constructed
primarily for recreation or education. Then he has to believe that it meets acceptable
construction and design practices.
