My first Windows XP Embedded post - DUA feedback?

OK, I know I've focused my posts thusfar on setup experiences and technologies, but I've been working on a project on my new team - Windows Embedded - and I am hoping to solicit some feedback here. Are there folks out there using Device Update Agent (DUA) to maintain their Windows XP Embedded images? I have run across some oddities and difficulties as I ramp up on the technology and I'm curious what experiences everyone else is having. If you have any comments, suggestions, complaints, feedback of any kind please let me know. I'd like to pool all of the feedback I get and all of the things I can find on newsgroups, etc and figure out what we can improve on specifically in the area of servicing and adding new components to existing embedded images. Thanks in advance!
