AirPort Express + GBit-Switch = AirPort Extreme?

[Giuly]

Hi,
I have a Fritz!Box, and it doesn't play nice with Bonjour (.local-domain doesn't work, it uses fritz.box-domain). I want to upgrade to 802.11n and 1000Base-T anyways. Can I hook up a 1000Base-T switch to the AirPort and connect it to the Fritz!Box with everything except routing disabled?
Does the AirPort Express provide the same features as the Extreme then? I need an extra switch anyways, that's why I rather want the Express.

The ether port on the express is 100BaseT.

If you don't mind the bridge between wired and wireless being only 100 Mbit, then it should work fine. 802.11n has a "usable bandwidth" that is barely above 100 Mbit, even at "300 Mbit" mode, so you shouldn't see an appreciable difference between that and having the 802.11n AP inside a Gigabit switch.

Airport extreme can have wired clients from it's router. An Express is either a wireless-only router or just a bridge with something else routing.

That being said, unless you want the speaker capability of the Express, go Netgear or DLink.
