I am planning on buying an Xbox here in the next month or so. I have a wireless network using an Airport Extreme base station. In order to hook up the xbox to the internet, I will either need to run an ethernet cable through the house from where the AEBS is to the xbox.....or.....get the MS wireless xbox adapter. So rather than spend $100 on an MS product, is it possible to use an Airport Express and plug the ethernet cable from the Xbox into this? The advantage would be that I could then also use Airtunes to stream music from my MBP. I have read there might be some security issues. I am not running n mode - just mixed b/g. I also have WPA2 security enabled rather than WEP. Thanks for any help. Howard.
