You may not be getting the answers you want here because it's quite possible nobody knows. I would say this is one of the times I'd go use one of my developer program support incidents (in fact 2 out of 3 I have used have been about networking and I've gotten great answers).
The names CFStream and NSInput/OutputStream really suggest you want a stream socket underlying them, not a UDP one, but I can't find a thing in the documentation which actually says that.
The only three ways to find out for sure are to write some code to test it, or use a support incident, or search the developer forums.
If you search the developer forums for 'CFStream udp' you may find out whether UDP sockets can be wrapped in a CFStream and may find an answer about whether UDP sockets can be backgrounded using the VOIP key. Make sure you search back more than the default 90 days to find your UDP answer. I can find only one post about each of those, however they're both from people whom I believe know what they are talking about.
