I've got to appreciate Julie's determination: XmlFormViewer In ASP.NET Application

While my team has worked on breaking the InfoPath.exe rich-client bits into a hostable control, our Form Server team also took on the work to make the server technology hostable in ASP.NET pages.

So whether you have a rich-client need to host a structured XML editor or a thin-client browser need, we've got you covered. I can' encourage people enough to take the time to understand InfoPath fundementals so that they next time you're dealing with the need for a rich-form editing solution, you can just turn to InfoPath and save your self time and money.
