i don't think we'll be truly able to build a system until technology comes up with a free floating personal video assistant. eg. a digital page to follow the squire around, floating above you or something like that. chip embedding might be another option i guess.

I think the technology is already available. Of course, not yet integrated into a functional system. The little iPhone like camera could be implanted on your forehead and powered by a tiny rechargeable battery embedded inside your chest (like a pacemaker) together with a miniature circuit. Video would be buffered on an internal 64GB solid memory and continuously transmitted via 3G network to a centralized storage facility. the 64GB buffer would be used when wireless was not available. With 64GB you could store about a day worth of highly compressed (YouTube video like at about 1000kbits/sec) of continuous video before you an out of memory. Hardware wise it could be mass produced for less than $100 bucks. Wireless costs would be expensive but as they go down in time more affordable.
