The placards made clear this was not your typical immigrant rights march: “We played by the rules, now it’s your turn,” read one. “Legal immigrants keep America competitive,” read another.

High-tech workers here on federal permits are speaking out — many for the first time — over rules that leave them in personal and professional limbo.

After Congress failed to reform immigration laws for the second year in a row, hundreds of the largely India- and China-born workers protested this summer in Silicon Valley and Washington, D.C. They were frustrated that the divisive debate over illegal immigration had overwhelmed efforts at comprehensive immigration reform.

“I’ve never held a banner before, but I don’t know what else to do,” said Gopal Chauhan, a high-tech employee who has been waiting seven years for a green card. “We usually have better things to do, like invent the next iPod.”

Legal immigrants who feel squeezed by limits on the number of green cards issued each year are trying to separate their complaints from the protests by illegal immigrants. And high-tech companies that say they can’t fill jobs because of a cap on skilled-worker visas have stepped up their long-standing plea for the cap to be raised.

EBay division Skype and mobile phone group 3 have launched a mobile handset that allows Skype users to make free Internet calls to each other while on the move.

The companies said on Monday the new 3 Skypephone could also send free Skype instant messages, and that they hoped to sell “several hundred thousand” units worldwide in the fourth quarter of this year.

NBC and Fox are set to launch an advertising-supported online video site that hosts programming from varied entertainment companies in a bid to seize viewers from Google Inc.’s YouTube, the broadcasters said.

A test version of the site, Hulu.com, goes online Monday, with plans to premiere a final version in a few months, company officials said.

The site, developed by News Corp. and NBC Universal, a unit of General Electric Co., offers free viewing of full-length films and TV episodes, supported by advertising.

It will host programming from the two networks, as well as TV shows and films from Sony Corp. and Metro-Goldwyn-Mayer Inc.

“Consumers identify with shows and films,” rather than networks, Hulu chief executive Jason Kilar said. “When you aggregate great content together, it makes things easier for the user.”

Walgreen plans to put kiosks that can make DVDs of popular movies in drugstore photo departments next year, using a new system that would increase selection while avoiding piracy.

Recent change in copy-protection rules governing DVDs have freed Walgreen and other retailers to tap this new movie market by letting consumers burn digital copies onto blank discs at stores, industry watchers said.

Walgreen and CVS have tried to attract more customers in recent years by offering improved digital photo kiosks, in- store health clinics and exclusive merchandise.

For studios, the kiosks add to revenue, particularly from older and more niche content selections, without having to manufacture, ship and store them.

In the 1970s, Vint Cerf played a leading role in developing the Internet’s technical foundation. For the past seven years, he’s faced the more daunting task of leading a key agency that oversees his creation.

After fending off an international rebellion and planting the seeds for streamlining operations, Cerf is stepping down this week as chairman of the Internet Corporation of Assigned Names and Numbers.

“My sentence is up,” Cerf said with his characteristic sense of humor, which he and others credit for helping him steer the organization through several high-profile battles from which it emerged more stable and stronger.

Cerf, 64, who’s also a senior executive at Internet search leader Google Inc., joined ICANN in 1999, a year after its formation to oversee domain names and other Internet addressing policies. Cerf was elected chairman in 2000 and leaves the unpaid position after Friday’s board meeting in Los Angeles because of term limits.

When he joined the board, many questioned whether ICANN would survive. Now - though some people still complain that ICANN is arbitrary, secretive and slow - the focus is more on improving it than replacing it.
