I think given the complexities of growing nanotube forests in the first place, attaching it to a cheeseburger isn't much of an issue.
Dear Mr Bitslice.
Thank you for submitting your concept for a McDonalds "Stealth Burger" that our customers won't actually be able to see, together with your proposed commission schedule. Regretfully I must inform you that our marketing experts have advised that the significant cost of this venture is unlikely to be recouped in increased sales. Further, our legal team seem to think we will get sued six ways from Sunday and will be bankrupt within the year.
As ever we do appreciate your "unique" suggestions as they brighten up many an otherwise routine executive meeting, so please come them coming.
Yours sincerely,
Ronald.
