Switch all of your machines from XPE to W2kP, or better yet, make the whole lot Linux. Its cheaper and better...
I don't know if LabVIEW will run on the 610. I know that LabVIEW for linux runs on RedHat, but I have no clue about processor compatability. You can try to run it, but you may have problems. Contact NI and find out. Also, check out ni.com/linux, you just might find something there.
Windows XP has been reported to have some issues, and I don't believe that all of them are known. Windows 2000 is based on NT, and LabVIEW probably runs best on this platform (among Windows platforms.)
Good luck. Sounds like fun.
