I'm using Windows XP Embedded with LabVIEW 7.0 built applications. The main difference between XP and XP Embedded is the fact that you can strip out as many components from the operating system as you want. Because it is still XP underneath it all I haven't seen any issues running LabVIEW on XP Embedded compared to plain XP and you shouldn't need any additional help from NI to run on XP Embedded. The biggest issue is simply learning how to use XP Embedded. It can be fairly complicated depending on what you want to do. My goal was to boot and run my program from CD and without any hard drives. I was able to do this but it was much more complicated than I expected.
There is a good book for getting started called "Windows XP Embedded Step by Step." For more complicated issues search msdn.microsoft.com and post questions on the microsoft.public.windowsxp.embedded newsgroup. One piece of advice I would give you regarding LabVIEW is that it is a lot easier to build your XP Embedded OS first and then install your LabVIEW application after you're done with the first boot on your target machine. It is much harder to include you're application in the build.
