You have managed to get a very solid and simple Nurbs app here, great work. I think alot of people don't get into Nurbs due to the cost of the packages and the amount of functions they have, so they get intimidated. Any idea on the cost of MoI once you're ready for release?

Here is a quick doodle done after downloading the beta. The UI is so unitimidating that you can just get right into modeling, you have compeltely accomplished you're goal of quick idea creation.

For anyone new to Nurbs I would reccomend MoI in a heartbeat. I've posted on a couple of forums as well to help spread the word.
