From Infendo:
"Yesterday Nintendo opened up a new page for it’s forthcoming Wii Video Service Channel “Wii no Ma.” The channel, which will be released in Japan on May 1st, allows you to populate a room with up to eight Mii’s to live in a real time virtual life while you watch and rate original videos that are delivered through the Wii’s internet connection.

But the “Wii no Ma” room isn’t just a stylish Japanese table and a slick flat-panel TV for your Miis to enjoy. You can also use the in room calendar to get information and trivia about different dates and holidays, and travel to different partner businesses (say a fast-food chain) to download coupons to your DS and use at an actual store, or even sign up for free samples to be delivered right to your door!

Sure it is exciting that you can sync videos with your DSi to watch on the go, but not if the videos aren’t any fun to watch in the first place. And with the vague promise of original content and no established series or shows it’s really anyone’s guess whether the “family friendly programming” will have more in common with the Discovery channel, or a video-segment on Sesame Street. On the other hand, new and original content could be just what the Wii needs to push it ahead of competing consoles video-services that focus mainly on media you can buy and see elsewhere."

Would it be called Wii no Ma in the US?

If I literally translated it, you'd wind up with "Ma's Wii" as no is usually a posessive. As for what "Ma" means, here's the first thing I found:

"Ma means an interval in time and space, but it is much more than just a blank space. It is best described as a concept related to commenting on, or engaging in, the Japanese arts such as: Kabuki, Noh, dance, storytelling, music, calligraphy and painting. When ma is used in conjunction with the arts it relates to rhythm and berating (it was originally a concept related to music). It can best be described in theater as a dramatic pause in spoken lines, in music it is interpreted according to each musician's taste and how one wishes to space the notes. In painting, the empty space (ma) is used to enhance the whole of the painting."

So I guess that clairifies the title a bit but I'm not sure what they'd call it here if they offered it.
