RAMALLAH, West Bank  Nibbling doughnuts and wrestling with computer code, the workers at G.ho.st, an Internet start-up here, are holding their weekly staff meeting  with colleagues on the other side of the Israeli-Palestinian divide.

They trade ideas through a video hookup that connects the West Bank office with one in Israel in the first joint technology venture of its kind between Israelis and Palestinians.

“Start with the optimistic parts, Mustafa,” Gilad Parann-Nissany, an Israeli who is vice president for research and development, jokes with a Palestinian colleague who is giving a progress report. Both conference rooms break into laughter.

The goal of G.ho.st is not as lofty as peace, although its founders and employees do hope to encourage it. Instead G.ho.st wants to give users a free, Web-based virtual computer that lets them access their desktop and files from any computer with an Internet connection. G.ho.st, pronounced “ghost,” is short for Global Hosted Operating System.
