the_prashn t asked:
I have a PowerPoint presentation that I want to observe any people for a month but should be able to copy it. 1. Can I disconnect the Internet from a car, arrange the files there and ask them to use that machine (further removing / which renders invalid the USB sockets and other external). what else? I want to put the files somewhere in the power network and give them some "viewers" special, which will display the files from a URL in such a way that can not keep to their local disk. Solutions opensource / free?

you could convert the powerpoint presentation to shockwave flash format (swf), that way you can post it on a site and viewers can’t save it. well, there are ways to save it but it is a little complicated for the average user.
Or you can make it a movie and post it on a youtube like site.
