Summary Box: Censor sought for Pakistan's Internet
WANTED: Pakistan is advertising for companies to install an Internet filtering system that could block up to 50 million Web addresses.
THE WORRY: Free speech activists fear current censorship could become much more widespread. Internet access for Pakistan's some 20 million Web users is currently less restricted than in many countries in Asia and the Arab world.
UNKNOWN: One person who sits on the board of the government-run technology fund seeking proposals for the blocking system says there had been many expressions of interest to create the system, including from two Western firms. He wouldn't name them.
