Intava thinks thousands of little sites can boost the wireless Web.: "Aside from technical limitations, a common complaint among consumers and industry analysts alike is that there's not a whole lot to access. Intava, a startup company whose software allows the 'little guys' to build wireless Web sites, hopes to change that. While there are at least a dozen so-called wireless development platforms already, they cost thousands (and sometimes hundreds of thousands) of dollars. Intava's product, dubbed Gravity, will sell for less than $600."
