Airport Express - iTunes streaming and wireless bridge at the same time?

Question

I know the Airport Express (AX) can do iTunes streaming. And I know it can act as a wireless bridge - meaning, a wired device can plug into the AX as if they were plugged directly into the local network.
What I am wondering - before I buy one - is whether the AX can do both at the same time. I have been reading around, and some people say it cannot, but I am getting the feeling that might be an older version perhaps.
Here is my set up -
office:
cable modem > Airport Extreme 802.11n base station
desktop computer
family room:
DVD, TV, TiVo, etc. -- all would like a wired network connection
Stereo -- would like to stream iTunes from desktop computer
So can the AX stream iTunes to the stereo, AND serve up the network to the TiVo, etc. at the same time?
If so, I assume I can plug an Ethernet Switch into the AX and have it simultaneously service >1 device (e.g. TiVo, TV, etc.).
Thanks a lot!

Answer 1

The newer 802.11n AirPort Express Base Station (AXn) can be setup in any of the following three configurations to enable its Ethernet port to provide network connectivity to wired clients:
1) As a remote base station in a WDS with another 802.11b/g/n AirPort.
2) As an extension to another 802.11n AirPort/Time Capsule.
3) As a ProxySTA (Ethernet bridge) with any wireless router.
I have verified that it can support both performing as an Ethernet bridge and stream simultaneously for the first two configurations, but have not had an opportunity to try the last to verify that case as well ... but I believe it should.
