DS WiFi On The Way
Edge Online reports that Nintendo's DS WiFi service will be launching in Europe as soon as November 25th. From the article: "As explained a few weeks back, Nintendo plans for the system to be safe, secure and easy to access. Players will be able to access the WiFi Connection service via hotspots in their local shop, their internet service at home (shared with the USB dongle) or via public hotspots. Nintendo Europe is still in the process of signing a deal with a telecomms operator to make the latter work, with an official announcement due shortly." Gamasutra has coverage of the WiFi announcement as well, with details on a Nintendo branded adaptor and new wireless titles.
..this is a solution for people that do not yet have wireless in their homes? (single computer with an internal PCI DSL modem, for example) It seems that it merely performs the wired-wireless bridging, unless there is something else that I'm missing...
I'd like to be able to play online at home but I'm not about to turn off encryption to do it.
Then allow only Nintendo's range of MAC addresses to connect without encryption. Your router does support that, right?
if you're playing on an untrusted network, how easy would it be for people to grab your username and password?
If authentication data is encrypted (for example, SSL with Nintendo Co Ltd as the root CA), then there shouldn't be much of a problem. The public Internet isn't "trusted" either.
