Once realestate.mobi is developed this will likeky get some traffic.
To chime in on the general .mobi debate, I think it will work as intended just as long as the mTLD people invest some of their new found reg and premium sales money into the marketing effort that is needed over the next 3-5 years. Browsing on a mobile device sucks right now because the sites aren't built for it. If I know I can go to a .mobi and it will work then I will use it. To browse another tld will be a crap shoot for several years to come. But the content needs to be on the .mobi sites, not just a bunch of SEDO parking pages. The RFP process will help a lot with this because they mandate delivery on the proposal or they take the domain back. I'm trying to do my part by developing many as well.
