I agree on the line what @mobi72 has to say and would add that if this becomes a reality and the project is successful we would gee a huge demand for the product. As far as I can see is that currently there isn't any product like that which enables you to charge your battery from a mobile device - that's a unique feature that the cable would have and further adding other features like data synchronization and share makes it further an appealing product. But I do feel is that the price is at a higher end though. Great hunt mate.
