Can we load all the files directly from server

We are a learning based company and were planning to do a game based learning. Many of our clients dont want anything to be installed on their machines as it has to be installed in hundreds. Is there a way where we can run torque files in browser without having to install any players.. I want my games' data to be streamed or loaded directly from a server during run time or can be preloaded. Can this be done? I read somewhere that halflife game can be played inside flash player 10 . Can something similar be done for torque also? Pls suggest.
