Technology for Undercover Journalists?

Undercover Journalist asks: "I need to take pictures and video in an area where soldiers/police will try to stop me if they saw what I am doing or/and confiscate my equipment. I need a rig that will allow unobtrusive taking of video/pictures and a way to transmit these images out as soon as I take them. I am thinking on a very small digital camera that can link to a notebook/pda that will spool the stream and use wireless to send the stream to a back-office for emailing it. Preferably, I should be able to script things, e.g. automatic, hand free operation and self-delete of files after transmission. The equipment should be at consumer level pricing. I don't have CIA budgets. I would appreciate thoughts about the kind of rig that would work best."
